Trusting your life to the orders of a judge and have no Plan B in case they are ignored may lead to an early grave staying. He was a convicted felon with a history of violence.
The idiot was armed with an M1 carbine, a Ruger 10-22 and a Ruger Redhawk. Unfortunately, the resident that stopped Mancilla, Gary Gowan, died exchanging fire probably saving a lot of lives.
UPDATE: It was worse. Just found this follow up article.
This kind of judge used to be the exception, but now they are the Soros rule.
