Too Bad We Have To Have Police Officers

I was driving down Hwy 16 today and saw a State Patrolman who had pulled a car over. As the officer leaned forward from his position near the back right passenger door to peer into the front passenger window at the driver, I'm sure the driver had no idea the officer had his right hand reached around behind him clutching his gun. First of all, how scary is it to know that when a cop is contacting you he has his hand on his gun just behind his back. But what's even more scary is the fact that there is actually a job out there where you have to have your hand on your gun every time you talk to someone.
