Wait, what kind of crime? I am not using tik tok, i always thought its for 15 year olds. So what kind of crime is posted there and who would be so daft to post incriminating video footage of themselves? And even if true, if this is owned by china, and I smoke a joint in front of a camera...what are they gonna do? They do not know where I am, who I am and who has jurisdiction. If they report me to the canadian authorities, they are sol, it is widely legal to smoke that in CAD. If they report me to the uk government, nothing will happen. If I never go to china, nothing will happen, so what is the basis of your thoughts on this?
