The problem is the police are damned if they do, and damned if they don't. Even is it does upset people, I would rather the police have powers to stop and search than see another 7/7. I vividly remember that day - for hours I had no word from my family and thought they were dead, and it was the longest day of my life. I'm sure those who were injured or lost loved ones aren't complaining.
Tillyfloss doesn't feel safe, and neither do many others - including me.
Gromit, "There can be no end of freedoms that can be curtailed with the Prevention of Terrorism Act'". Hopefully one freedom that will be curtailed is the freedom to blow people to smithereens.
