bottom line, in todays society and governments...if you are in the USA, our opinions or stories dont matter when it comes to this topic....for YOUR OWN PERSONAL WELL BEING if you DONT disclose BEFORE exposing someone to it knowingly, YOU CAN and most likely will be charged with a felony and possibly imprisoned.
It's not a joking matter, or fairy tale, nor is it subject of a "story line"...it's a reality that you must face. sorry if its not what ya expect to hear, but it only takes one person to get authorities involved, then from that point your fate is at their mercy. if you do some research, most who dont disclose and get caught at it, are getting charges like attempted murder with intent, etc. i cant speak for the other countries, but in america every state has disclosure laws.... Good Luck!
