They apply for and are granted all the necessary permits etc.
v: I’d like to know how these idiots fund their protests.
Lawsuits! When the WBC takes its show on the road, they are accompanied by lawyers and vidiographers. Whenever a threat to their First Amendment rights is perceived it is duly recorded. Since the WBC is in that jurisdiction legally (see above) they will threaten a lawsuit against said jurisdiction for failure to protect their First Amendment rights. The insurance carrier for said jurisdiction will almost always settle rather than face a drawn out legal fight.
I’m disgusted that a permit would be granted to protest in front of a school, during school hours with those signs (the paper posted one pic on the facebook page...at least one Thank God for Dead soldiers sign is visible). Again...if I were a parent of a student there...
