Max & Bus Security

For Max and Bus to have security, those cameras are for the most part, useless. The tapes are unmonitored, the only way the tape gets viewed by officials is AFTER something happens. I can understand the busses not being monitored, but the Max should for the simple reason the operator can not see what is going on in his/her train cars. I went to the Expo center last weekend, took the yellow line max. Security on the line????? WHERE??? Luckly as a passenger I am allowed to have my own protection against any disgruntled passengers.
