Why didn't Wilson use his Taser on Brown?
It is all one incident and happened over the matter of seconds.
Brown became a lethal threat by trying to grab the Officers gun.
The gun discharged in the struggle. The lethal threat had been established.
Brown attempted to flee the lawful restraint of a police Officer.
The Officer followed, but Brown refused to follow the commands of the Officer and instead charged.
That is a lethal threat continuing to be a lethal threat. You do not holster on such.
The shooting was justified.
"The law is reason, free from passion."
