I feel extremely strongly about this so will try to resist getting involved to much with some of the comments here, but I will say this, the campaign is a joke and is just another piece of the puzzled needed to control the public.
Personally at least, I would rather the BTP go after the fare dodgers, drug/drink addicts as well as the disorderly. Looking out for potential security threats in the forms of bombs, weapons etc should be there number 1 prioity, not Dave who happens to find Emily attractive and gave her a second look which she didn't like.
My quesion to everysingle one of you who support this movement is, have you never seen a woman (or a man depending on gender/sexuality) that you liked the look of and though "damn, he/she is fire" and gave them a second look? If you haven't, well done, if you have then you're in no position to comment as not every man who looks at women is a massive nonse, some of them just like what they see and would never take it any further than just a look unless the woman felt the same about them.
Don't moan at men who look at women if you have ever done it yourself, whether that be on the beech, at work or on a train, it's hypocritcal.
