More cameras does not equal more security. They aren't put there to protect your property in the same way that HR departments don't exist to protect employees.
No, they're put there to collect grainy images of the perpetrator to distribute after the shooting. It's sad/ineffectual, but still far less nefarious than TFA makes it sound.
Right. 1,300 cameras for over 50,000 people in a hundred or so multi-story buildings spread over a couple of hundred acres...seems proportionate. It's maybe a dozen cameras per building on average?
I'm not a fan of surveillance per se, but acting like this is disproportionate is just silly.
