About as well as could be expected...

Many teachers and their unions fiercely rejected the president’s suggestion [to give guns to teachers], but one Stoneman Douglas educator, Sean Simpson, said he would consider it. “There are some of us that are willing to take the training if it was offered and probably be another line of defense,” Mr. Simpson, a chemistry teacher, told MSNBC a week after the shooting at the school, in Parkland, Fla. He cautioned, however, “I’m not sure if it’s the answer.”

Turns out he was right: arming teachers is not the answer...

This past weekend’s events may provide a clue. Mr. Simpson was charged on Sunday with failing to safely store a weapon after he accidentally left his Glock 9 millimeter handgun at a beach restroom, the Broward County Sheriff’s Office said. By the time Mr. Simpson realized it was missing and returned to the restroom, at the Deerfield Beach Pier, a homeless man who was drunk had picked it up and fired a bullet into a wall.

It always seemed to me that the kind of teacher who would want to carry a gun in school would be the last person on earth you would want to carry a gun anywhere. Thanks for proving me right, Mr. Simpson.
