One question, how did they find out? Did the moron show it to someone. The first rule of concealed carry is don’t talk (brandish) about concealed carry. People that you think are you friends WILL burn you.
From the article.
Rueben Littlejohn, the San Diego School District’s police chief, has said that staff members at Farb Middle School said they heard Walker was keeping ammunition in locked cabinets in his classroom. He also told students and staff that he had a gun and loved firearms.
Police checked the cabinets but did not find anything improper.
Officers contacted Walker, patted him down and found a .38-caliber semi-automatic pistol with a seven-round magazine. They also found a knife with a 2½-inch blade.
