People are afraid of police because do scary things to people. From James Bovard at fff.org:
Police in Tempe, Arizona, announced plans in July for a “positive ticketing” campaign to pull over drivers who had violated no traffic laws. A Phoenix TV station reported that the police would give the people they targeted free soft-drink coupons for Circle K as a reward for their “good driving behavior.” Police in other areas have run similar programs in recent years but the TV news report on Tempe’s plan spurred a torrent of testy Tweets:
“Keep your hands on the wheel and don’t make any sudden moves while you are being rewarded, it could cost you your life.”
“We gunned him down…. well, he refused to stop for his coupon. Self defense. Case dismissed.”
“Um, WHAT?!? They better not stop me for driving legally cause that’s illegal! #harassment”
“What if you don’t stop?”
“Cops to profile for illegal immigrants under the guise of campaign to promote good driving.”
“There goes probable cause right out the window. Police state 101.”
“I would get a panic attack. My reward for driving well is not dying. That’s all I want.”
“Unless it’s a ruse to illegally search your vehicles. And if they notice anything out of line during the mock pullover you’ll be arrested.”
“What’s next? Are they going to start walking into people’s houses to congratulate them for not breaking the law?”
One commenter suggested he could be fined for “resisting a coupon” for free drinks.
