While the image is fake. The sentiment itself is correct. Police should not be judge and jury and should not be shooting ANYONE for any reason unless there is immediate danger to someone else. Robbing a store doesn't constitute immediate danger. Even a big guy running directly at a police officer and tackling him to the ground is no reason to kill someone. Defend yourself, sure. But, if you pull your gun and shoot that person, you have just committed murder. and FF is a racist fucktard.
A big person running at a police officer, or any person is a danger. Your don't know what that person has in mind, or is capable of. The big person can be very capable of killing someone with their hands. And if he disables or incapacitates an officer, he can arm himself with a firearm. A taser may not even be felt by someone on drugs or a testerone induced episode. Immediately stopping the danger is the only option at times, hesitation can cause others to be killed or injured.
A lot of these questions are bad because the person who came up with them basically took them from the introductions to the Wikipedia articles of the answers to come up with the questions, without bothering to read the rest. Q2 is location dependent (eg, in mucous membranes vs blood); in Q1 two answers are correct (because one is a subset of another); Q3 no answers are correct because the “correct” answer is actually the group of genes that code for the correct answer, etc.
There are billions of ways to avoid that. Believe me, I have 4 brothers. If killing someone is your first response, you shouldn't be carrying a gun. Period.
