Ive been in this situation before and it SUCKS! I was delivering pizza ages ago and was on my way to a delivery when a cop pulled me over. I wasn't doing anything wrong so I was kind of confused, but pulled into a parking lot and parked. The cops got out and immediately pulled their guns on me and took cover behind their cruiser. Within seconds, there were 4 more cop cars pulled up and surrounding my car. I had 5 cop cars surrounding my car and at least 7 cops all with their guns aimed at me and screaming at me to get out of the car. I was freaking out! Ive dealt with anxiety issues my whole life and this caused me to have a huge panic attack, which pissed the cops off more, because it took me a minute to comply. It wasn't till I was face down on the asphalt (in the rain btw), till one of the cops said something like "hes just a pizza dude, this isn't him", and all the cops got back in their cars a sped off. It took me a good 15mins before i was able to catch my breath and calm down from my panic attack, and hours after that before i could stop shaking. To this day, anytime a cop gets behind me, I start having anxiety attacks and have to consciously try to calm myself down.
