The media advisory from NoIslaminschools.ca, the folks behind various protests re Muslim prayers sessions at Valley Park Middle School, describes the "mystery" speaker for their upcoming fundraiser as:
...a 9-11 Survivor & 1st Responder on the Bucket Brigade will be the Keynote Speaker. A leader in the fight against the New York City, Ground Zero Mosque, he has been on Fox News, CNN, ABC, CBS and a Documentary on the Ground Zero Mosque.
But if you run the various key-words through Google they point pretty clearly to standard-issue American Muzzie basher Tim Brown, of the 9-11 Families for a Secure America, itself an off-shoot of the Federation for Immigration Reform, both which groups might safely be described as far right, a few cans short of a six-pack, and etc. Don't know what the big mystery is supposed to be. As far as I can tell, Mr. Brown doesn't have any trouble crossing borders.
In any case, equating the ground zero mosque with the cafeteria at Valley Park seems like more than a bit of a stretch.
Tim Brown speaks out here.
