Police are seeking Town Meeting approval to equip officers with “electronic control weapons,” more popularly known by the brand name Tasers. The devices deliver electric shocks that cause temporary uncontrolled muscle contractions, incapacitating suspects so police can subdue them, according to Deputy Police Chief John Carmichael. He said providing Tasers to officers would give them another option when dealing with dangerous situations. “We’ve had several situations recently where officers had to draw a firearm when they could have used something less lethal,” Carmichael said in an interview. Police asked for about $44,000 to buy 40 Tasers — one for each officer — but are open to spreading the purchase over two years, he said.
