I didn't know Canada does have serious problem with crime in Saskatchewan. I'm from Kansas, USA. It is a bit more flexible and we do have high crime in one of city in Kansas City, KS and Kansas City, Missouri (city straddle between stateline). I live far from it. Yes, We have Homeland Security do the check if something goes bad on Facebook. Basically, they'll send email or member's weblink a warning. I recalled 7 years ago that We had a warning Email from AOL ( I was member of AOL back then) stating that telling me and rest of other to stop Flaming (cuz one deaf sending out flame email). It wasn't my fault cuz I was not involved but someone had my Email on their mailing list. I recalled received email from one angry deaf about deaf guy who stole her car and credit card ect.. stuff like that.
So given idea that Facebook will send out warning first. If not resolved then they'll cut off membership. If person subbornly sign up in different name in Facebook and do over, they'll send out cops to investigate. If death threat, they'll call Homeland Security and I'm sure they'll send SWAT team over to person's house. (in USA).
