The white school shooter in Michigan has already been charged with terrorism, they've already decided that he's going to be tried as an adult, and his parents have been arrested too. It's amazing how fast the government can move when they want to.
The black school shooter in Texas, on the other hand, made an excuse that he was being bullied and they let him out of jail the next day. lol. Some school shootings are a big deal I guess. Others, no so much.
