US: Police officer playing with laser pointer on Taser forgets that Taser is armed; tases colleague

A police officer who was “horseplaying” with the laser pointer on a Taser, forgot that the weapon was armed and accidentally tased a colleague.

On March 27 2018, Officer Dan Sells of the Lafayette (Indiana) Police Department was in a hospital conference room for a debriefing, along with two other officers and a dispatcher. Sells and another officer disarmed their Taser stun guns and began shining the Taser’s laser pointer (used for aiming) at the dispatcher.

Sells became distracted for a few minutes. He then picked up the Taser, intending to continue the laser pointer horseplay. However he forgot he had armed the Taser. When he pulled the trigger to turn on the laser pointer, the Taser fired, sending the electric prongs into the dispatcher’s foot.

He received a five-day suspension for unbecoming conduct, unsatisfactory performance, misuse of department equipment and misusing a weapon.

On May 30 2018 Sells agreed to a 10-day suspension for apparently unrelated charges (in a separate incident) of unbecoming conduct, unsatisfactory performance, and violating evidence-gathering procedures.

China: Two students with macular burns from laser pointers

Two Chinese students have been treated for eye injuries caused by laser pointers.

In the first case, the macular area of a boy’s eyes were damaged so that he could not see an object at 10 cm. The damage was confirmed by retinal examination.

In the second case, a 15-year-old high school student also has burns on his macular area, from when a classmate aimed a laser pen at him. He could only see objects within 50 cm, and there were scars consistent with those left by clinical lasers.

Both cases were reported by Xie Airui, an eye specialist at the Ineye Hospital of Chengdu University of Traditional Chinese Medicine. Both cases occurred between September 2017 and May 2018.

According to a May 31 2018 news story, laser pens have become popular with some schoolchildren in Chengdu. Many stationery shops sell them for prices between USD $0.80 and $31.00. in 2014 the General Administration of Quality Supervision, Inspection and Quarantine warned consumers about laser pointer hazards. “But no market supervisors have taken up the matter in a serious way, according to Xu Bin, a lawyer in Chengdu.”

Ukraine: Six soldiers said to be injured by Russian-backed laser weapons

The following material in blue is from the Kyiv Post, May 28 2018:

At least six Ukrainian servicemen deployed to the Donbas war zone have suffered serious eye damage from unidentified optical radiation devices used by Kremlin-backed militants on several occasions since 2016.

The military believes that the soldiers were likely targeted with blinding laser devices, which Russia brought to Donbas in order to test this new advanced technology in battlefield conditions. If independently confirmed, the usage of such weapons can be qualified as a war crime, according to international law.

Since the war’s outbreak in 2014, there have been at least three such incidents recorded by the State Border Service and the Ukrainian Ministry of Defense.

On July 18, 2016, three Ukrainian border guards deployed to a forward checkpoint between the city of Maryinka just west of Russian-occupied Donetsk suffered severe eye injuries as they surveyed enemy territory in front of them through binoculars and monoculars.

India: Laser pointer misuse in 2002 said to cause riots and close 600-year-old religious shrine

A May 1 2018 news story about a 600-year-old Indian shrine states that the shrine was closed in 2002 after a riot broke out, instigated in part by misuse of a laser pointer.

The shrine of Madhin Saheb was built in 1444 in Srinagar, a city in the Kashmir Valley. In the late 20th century, the shine was popular with locals and tourists. Sunni and Shia Muslims worshipped together inside the shrine. The article states:

The peace was, however, broken in 2002, after a rumour spread in Srinagar that some miracle had happened inside the shrine. The rumour spread like a wildfire and a number of people rushed to the shrine. Though there are different versions on the incident, the largely accepted one is that Shias claimed that the outer wall of the shrine had some blood spots on it and a “Shia flag was miraculously erected on the roof of the shrine, hence the entire monument belongs to them.”

“It was a mischief done by someone. The blood spots were actually a beam from a laser pointer, a trending device then used as a source of amusement,” says Ghulam Nabi, 62, who was among the hundreds of people present on the spot that day.

He says that soon after this act, riots broke out near the shrine and its adjoining areas leaving many people injured. “It was chaos all around. No one from either sect was ready to listen. It was only after tiresome efforts by police and civil administration that the situation was brought under control,” Nabi says. Following the incident, Department of Archives, Archeology & Museums sealed the shrine, and since then, entry to it is restricted.


The director of the Department of Archives was quoted as saying “Though there has been an improvement in the situation since the day it (shrine) was closed, we do not think that opening this shrine right now would be a reasonable decision. We respect the sentiments of people attached to the shrine, but we have to keep it shut till situation returns to normal. The monument will be opened one day. We see that happening soon, Insha-Allah.”

India: Laser pointers said to harass elephants

Amid a rash of captive elephants going wild in the southwestern Indian state of Kerala comes a claim that laser pointers have been used to provoke the pachyderms.

An April 12 2018 story says that although “[s]evere torture and unscientific handling” can cause problems, that laser pointers also may have been used recently by “a mysterious group with vested interests.”

According to the story, “There were complaints that light beams were shined continuously from a distance into the eyes of elephants paraded at the Sree Padmanabhaswamy Temple in Thiruvananthapuram and some other local temples in Thiruvalla and Pathanamthitta. It was alleged that the jumbos turned restive and violent after being blinded with the high-powered laser pointer.”

The story includes a 47-second video clip of an elephant refusing to get onto a truck, while a dot moves around on and near the elephant.

COMMENTARY FRO LASERPOINTERSAFETY.COM

An analysis indicates that the moving dot is not from a laser, but is from internal reflection in the camera lens of a bright light in the scene.

The screenshot below, from one second into the video, shows the dot circled in green, and a bright light circled in red.

elephant alleged laser Kerala India

As the video is played, the dot moves around. Its movements are correlated with the bright light. For example, when the elephant’s body blocks the light, the dot disappears. Because it is a reflection, it moves opposite to the light, and its movement also changes based on the tilt of the camera lens.

In addition, the dot appears yellow or white. This correlates with the light color. Yellow is very uncommon for laser pointers, while there are no “white” laser pointer beams. A green or red dot would indicate an actual laser.

While there may be other incidents of laser pointer misuse in Kerala, the moving dot in this particular video does not, in the view of LaserPointerSafety.com, show a laser dot or any actual (real-world) light on the elephant.

According to the news report, “[s]hining a laser into another person’s eyes in California is a misdemeanor with a penalty of up to 30 days in jail.”

UPDATED - March 27 2018: Blue-green light again was aimed into a Mission Hills home, on March 23 2018. It appears to be coming from the same apartment building as the January incidents. Footage shows homeowner Daniel Wang using a telescope to try to identify the specific location in the apartment building. (Note: A person should not use a telescope or binoculars to look in the direction of a laser, since the optics can focus the beam and make it more dangerous than looking at the beam with the naked eye.)
