Why would they jump to conclusions? Why would they know about it?. When you are 18 and buy an airsoft gun, it arrives to you in a styrofoam box wraped in shipping paper so no one knows what it is. You immediately buy a case from your local hunting or sports store and lock it. Then you take that case it hide it under your bed or someplace out of sight. You dont take it out in your living room with your friends to do some bunny hop videos. Keep it locked up so none of your neighbors whisper about you being some sort of criminal when you walk by and having false complaints called in about shots fired or illegaly stored firearms which will only make your life a living hell.
In short, never take it out and no one is the wiser. Where the heck did this tell the RCMP stuff get into your brain from?
