Lawsuit as a weapon, as CAIR practices in the US? Perhaps. From the [1] National Post, :

TORONTO - A Muslim man suing Ottawa for $1-million because he was detained and questioned about possible links to terrorism was seen videotaping a Toronto subway station in a "suspicious manner," say court documents filed yesterday by the federal government.

CSIS and the RCMP began investigating Kassim Mohamed in April after
numerous witnesses saw him filming a Yonge Street transit platform "in
detail" and in a manner that "appeared to be trying to hide the fact
that he was doing so."

The statement of defence comes two months after Mr. Mohamed's lawsuit,
in which the Kenyan-born Canadian says authorities suspected him of
having links to terrorism simply because he is a Muslim who filmed the
CN Tower with a home-video camera.
