I completely understand what you're saying.
So, I was in the Tucson Mall, Saturday afternoon, walking to my car after having purchased a gift card from the customer service desk. As I was leaving (calmly, politely, no threatening movements, not running, flailing, verbally assualting or otherwise engaging in any activity that could be construed as making myself a public nuisance or danger. I was alone.) a mall security agent started to shadow me (1 pace behind, on my left), that made me nervous, I asked if I could help him, he asked (with hostility) where I was going, I said my car, I asked if I was in danger that I needed his protection (sarcastically), he said yes, I asked from what?
That was when the other security guard slammed me from behind by my neck, I was thrown to the ground, pepper spray in face, then rolled over, head pressed into the ground by one of the other security guards (there are now three) and I was hand cuffed. I demanded they tell me what the hell was going on, they said to shut up. I asked for help, no one came, I saw the police, I yelled for them to come over and help me.
I said that I didn't know what was going on or why I'd been jumped. The Two officers came over, one on either side, grabbed me by my biceps, threw me to the ground and said "get the f**k up and start walking*. I cited my rights, they said "fine, you're under arrest, that work for you?"...and it goes from there.
