Wow, someone has been handing out the tinfoil wholesale in this thread.
So, let me get this straight...if I, while on duty, choose to ignore someone displaying a handgun in this manner, I'm OK--but an abnormality.
If I choose to contact the person--as has been mentioned above--in a friendly, nonconfrontational way--then I'm instantly violating someone's civil rights.
Can't win for losing, right? I guess that no matter what we do, we're not people doing a job. None of us have a sense of right or wrong, any sense of decency, patriotism, or compassion--put on the uniform, and I'm immediately a JBT, bent on trampling your rights into the dirt, being an oppressor to the masses, and a murderous thug at heart--right?
Oh--and to the poster saying that tapping them on the shoulder is an invitation to a "counterattack"--toward a cop in uniform?
Whatever, dude. Whatever.
