Of course there are terrorists, 9/11 and 7/7 wuldnt occur without them (also the IRA in the UK before that) The media overhypes the problem though, people want more done though enhanced fear. At the same time givernments want more control and now have a window to do it in the name of "terror prevention" and thats where things have the potential to go very wrong. cameras on street corners arnt always bad, they have convicted people of some pretty terrible crime in the past. Thing is there has to be a limit on these things. There is no point having 12 cameras on one corner or a camera on a corner where not a lot will happen.
