Airsoft guns are not firearms and DO NOT require a trigger lock. Personally I don't think they are a bad idea, but that aside, it's not like police never lie to intimidate or scare people.
I was once told by an officer that he could arrest me because I did not have my ID on my person at the time. He said he would be nice and do me a favour and let me off the hook with a warning. I laughed in his face.
Although I personally don't use trigger locks or locks on my gun cases they are certainly not a bad idea.
Few individuals would view themselves as barbarous, no, instead they view themselves in a different light, a distorted reality that justifies who they are and what they have done.
