They need those cameras for Internal Security la ....
To deal with terrrist attacks la
After the Boston Bombings , they have to do something quick now .
I think so ... of cos they wont reveal their motives .
Sounds like catching traffic offenders bla bla bla .... but fuck la , one stone can hit so many birds , no harm to say so .
Just in case terrorist attacks lah .
This camera will be useful .
