I've come across this material
from the ACLU on your rights as a photographer on several of the blogs I visit and figure it won't hurt to amplify the message. Bottom line? Law enforcement types generally have no legal basis to prevent you from taking pictures in public places or to confiscate your equipment if you've been taking pictures:
"Taking photographs of things that are plainly visible from public spaces is a constitutional right – and that includes federal buildings, transportation facilities, and police and other government officials carrying out their duties."
