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.
OMG a 2 1/2 inch blade. A pocketknife, just like the one I have carried since I was FIVE years old. That will be 60 years this fall. The only one who has ever been cut by my knife was me. Idiots...
Appears to be somewhat self-inflicted. The worst of all species to tell anything you want kept quiet is a child.
I am no lawyer, and I don’t play one on tv, but I think their pc is a bit light and without a warrant this should get tossed if he has a good lawyer.
