I received this information from a friend participating in the Blair County Tea Party. I know we're aware of this, but I thought I'd pass it along.
"...advise the folks to be very aware of security. ACORN has plans to infiltrate some tea parties and cause disruptions, act poorly, etc to give tea parties a bad name in the press. We would advise cooperation with authorities, a statement before hand that it is a peacefull gathering, a non-partisan gathering, and emphasize non-partisan. Any signs you folks make should be non-partisan.It only takes one or two idiots to cast an image on everyone, especially with a willing press. You have time to prepare for this possibility. There is no excuse not to."
"Also, Announce for folks not to sign any petitions or share personal information (Unless you have an official sign-up booth). ACORN identifies, isolates and attacks individuals and may have fake petitions that would not not be obvious, just to get contact information. You have to have some folks who are not "innocent" review things and be as prepared as possible."
