The entire scene in the future government law enforcement headquaters was filmed in Oakley's Foothill Ranch Main Offices. If you look at the backgrounds, you can make out the O's through the colored gels.

While Spencer is running from the law and takes refuge with the homeless, he needs a disguise to pass by security. The homeless man he's with says "wear these" and hands him Leather Mars (right like the homeless can afford that). I actually decided that I didn't like the Mars after seeing that, but later got them anyway.
