How do you judge the Canadian schemes to be excellent - have they caught any terrorists yet ?
That was "excellent" in terms of initiative. I don't think that "catching" terrorists is part of the scheme. Reporting suspicious activity quickly to the right authority is the key goal. I believe in fact that at one of the airports the local spotters were once responsible in reporting some sort of criminal activity which resulted in arrests and convictions. I'll have to try and dig that out somewhere.
