Handcuff and able to glitch out of the car

[Officer-Chris]

I’ve been seeing more and more of this. I’m not quite sure how people are getting out of the car while handcuffed. Is it possible to get child locked doors on the back of police cars?

I’m sorry if this is the wrong format! I’m doing this via cell phone.

Thanks!
