There’s a new push to allow all police departments in Pennsylvania access to radar guns. But not everyone thinks it’s a good idea. Right now, only state police can use them. Two bills in Harrisburg could soon change that. Sen. Jim Brewster, a Democrat from McKeesport, sponsored a bill that would allow local police to use radar guns to enforce speed limits. Pennsylvania is the only state in the country limiting their use to only state police. But the bill has opponents, like the National Motorists Association, which claims that radar, for local or state police, are almost exclusively used in speed traps. Brewster said his bill, and a companion bill, is getting support in Harrisburg.
