13u1as | why we still have laws preventing us to record officers during interactions with them | I would think this kind of accountability/documentation would be beneficial no only for the PR of Police Departments, but also for the court decisions, and for the well being of the public.
I understand certain states allow this kind of thing, while others the police will go as far to wrestle the camera from you.

5wc2d9 | what would happen to feet propped on an airbag if it deploys? |
On a regular basis, I notice passengers in other cars propping their feet on the airbag. It seems like an inherently horrible idea. I imagine bones snapping in many places, but what might exactly happen to someone who has their feet propped on an airbag, if it deployed in an accident?
