:I'm not worried about taking photos or running into HLS, I was just giving you a heads up since I've noticed you've taken several pics of POs...  I think the whole situation is stupid and smacks of paranoia  for instance, why would a "terrorist" even want to target the Santa Fe, TX post office, ya know??  If I were homeland security I'd be more concerned about the klan rallies in SF, than some guy taking a  pic of the local post office.  Anyhow, whenever I've been confronted I just smile, say "i see", and then wait until they're gone and snap my photos -)
