Don't know about Canuck law, but I'd sue them down to their underwear, if it happened here.
I think you'll see that happen here.
I would sue their pants off as well. BUT, I would have followed their directions to the letter and I would have laughed my butt off when they started asking about dynamite and illegal guns.....providing of course that I knew neither existed.
When you resist police you make their tough job harder and give them latitude for antics like this.
When you follow all directions they give and then they find nothing I am all for owning them to the tune of $$$$$ and even jail for offending parties involved in the raid.
If people do not follow orders given by police then you do so at your own risk.
Cops have a really hard job, I offer it is better to help them than it is to oppose them. When you cooperate and help them, and then find out they did wrong.....NAIL EM!
I had a friend who lived in an apartment complex the warrant for a drug investigation was for number 203. They hit number 302. They shoot the resident with a taser and cuffed the family then found out they hit the wrong number.
