That is a good question, and you are probably correct, a conservative might very well have pulled their gun.
However, in the exact same situation, they would have been rightfully arrested, charged, and probably convicted.
First, Grosskreutz had no concealed carry permit and was illegally in possession of a concealed weapon. So by law, any action he takes with the gun is illegal.
Second, since it was proven that Rittenhouse was defending himself, it would be illegal to shoot him. You can not legally shot someone who is defending themselves.
As any responsible gun owner knows, with gun ownership comes great responsibility. You can never legally use your gun unless you fully understand the situation. Grosskreutz admitted on the stand he did not know what was happening, he had heard shooting and he just ran up to Rittenhouse and pointed his gun at him.
Plus, while not really relevant, Grosskreutz was no alter boy.
A few days prior to him being shot, Grosskreutz was arrested for “prowling” and trespassing when he was nabbed videotaping the private vehicles of police officers in a police department parking lot at 1:00am.
In addition, He has an outstanding active felony burglary charge in New Berlin.
Prior to that, Grosskreutz had been arrested for beating up his own Grandmother and attacking an ex-girl-friend. He also was arrested for DUI, and had a previous weapons charge for illegal possession of a handgun.
