Call on them for what exactly? I've been robbed in my house at gunpoint, do you think you get a phone call in that situation?
Snow Plow hits my parked car, 8 hours later, a cop shows up, can't do anything.
If a cop is in the right place at the right time, maybe he can do something, or maybe like in front of the Empire State Building, he'll shoot 8 unarmed civilians by accident trying to get the bad guy. The threat of cops being out there is what keeps most people in line. When that doesn't cut it, they usually serve more as clean up and crowd control.
Too many cops now get away with crimes and it's gotta stop. Other cops see what they get away with and mimic the behavior, it's dangerous. Like I said, they profile all of us. They profile you, if you were to be pulled over, they would approach you ready to draw their weapon etc. A few bad people ruin it for all people. A few bad cops ruin it for all cops. It's just the way it works. Change your public image, you will see your support change as well.
The police were not always like this in this country. Post 9-11 it's only gotten worse.
