Safety cameras on campus really to keep us safe?

Cameras have been in place on the campus since October 2007. They were put on campus due to theft, but have served many uses to the campus police.
When the camera security system was installed, it was the first security system of its size on a CSU campus. Since then other campuses have followed the example. 
Since the cameras have been in place, vehicle theft has dropped by 76 percent. But that's not the only thing that police are keeping an eye out for. In 2009, Kris McConkie told the Daily 49er of an incident where the police came to invesitgate a group of students smoking cigarettes between buildings. McConkie said the police didnt say anyone complained, so they must have seen them on the cameras.
Recently the most students are concerned about the cameras in the parking lots. "If students are walking in with alcohol and it's clear, then that would be reason to send an officer. It's a violation of campus policies and it's against the law if they're underage," Lt Scott Willey said.
Many students have reported being caught on the cameras smoking pot in their cars. Although students know this is illegal, they feel its an unfair way to be caught and a violation of their privacy.
Carol Roberts-Corb, director of Housing and Residential Life, told the Daily 49er in 2009, "There may be a smaller minority that feels that the cameras are intrusive, while the greater majority feels safer."
