When being pulled over, you are not to exit your vehicle until the cop asks you to do so.
I dare you to run up to a cop waving your arms.
Is anyone even implying that the deaf man ran toward the police officer while signing?
Apparently from other comments, there's a lot of information that's been left out in this article. But I've been alive long enough and on FR long enough to see what has been happening with police seemingly using deadly force too freely against people and their pets.
Granted, there are elements that hate police and target them, but when one is enforcing the law and has the powers that are thereby granted, it should be axiomatic that such an individual be held to a high standard. Especially when a life is taken.
