But clearly though - this is a growing trend, don't you think? It may not affect you and you may not care, but it seems there are increasing numbers of photographers who are being affected by this, being accosted by security personnel with a dubious understanding of the law...

Personally, I feel this is not cool, and may be some sort of test bed for things to come. I think anything we can do, including writing to congressmen, etc., will be helpful.
