Andrew at Here in Van Nuys blogs about calling 911 after a pickup truck blocked his driveway and a man in para-military garb got out and began throwing things at houses on the street.

He gets back in the truck and puts something in his nose. He is doing something in his truck, assembling something, getting ready for....what? He gets back out of the vehicle and walks up to your neighbor's house and walks onto the property and throws something at the house. He walks up the block and back down the block and then back into his truck and reaches into his glove compartment for? This goes on for an hour...

The incident begins at 4:45 pm, Andrew calls the LAPD at 5:05, the weird guy finally leaves at 6:02 and the first police car doesn't come down the street until 6:10.
