Cameras are a weapon?

Yesterday, two peaceful protesters were arrested at a staged sit-in at MP Rob Nicholson's office. Read the full story here: Protestor arrested for filming police and watch a video of the arrest here: http://www.youtube.com/watch?v=iqNfE-r2AjA
The Niagara Regional Police claim that to film police is an arrestable offence and that cameras are weapons. Under the Canadian Charter of rights and freedoms, we are guaranteed the right to peaceful assembly to protest. These protesters were simply exercising that right and are now in jail without having broken a single law.

These officers must be educated in Canadian law and should be disciplined for their actions. Please write to the Niagara Falls Mayor Ted Salci, Police Chief Wendy Southall, your local newspaper, the Niagara Falls Review (local newspaper) and MP Rob Nicholson and tell them these police have acted wrongly. They have violated these protesters rights and should be suspended. The protesters need to be released immediately - without charges - and apologized to.

Today it is another who needs your help. Don't ignore this, tomorrow it could be YOU.

"THEY CAME FIRST for the Communists,
and I didn't speak up because I wasn't a Communist.
THEN THEY CAME for the trade unionists,
and I didn't speak up because I wasn't a trade unionist.
THEN THEY CAME for the Jews,
and I didn't speak up because I wasn't a Jew.
THEN THEY CAME for me
and by that time no one was left to speak up."
