We have had the what is, what is justified, when it should happen, how it should happen, what should happen to those that transgress and so forth but the "first time you noticed it" one is something I have not seen. This would be that then. Myself, I was watching a random western film with my grandma shortly after I started going to school and the bad gang were set to steamroll the plucky good village. However they appealed to the US army.... which sent a cannon with 3 balls and a bunch of uniforms. The leader of the bad gang saw through it but his henchmen promptly declared it unAmerican, pissed off and the day was saved. Now I am not quite sure if that was deus ex machina, Hays code, my general lack of knowledge of American culture, straight up censorship or something else entirely. However I was most annoyed that I was deprived of a bloodbath. UK cartoons were slightly odder than most of the US fare and decided less action heavy ( http://gbatemp.net/threads/what-were-they-smoking-cartoons.331874/ ). I did also wonder why nobody ever got shot in the A team. Games.... this was 1991. I am sure I could have had Nintendo's stuff explained to me at the time but it never occurred to me that it was. Never read comics and if I ever saw them then they were usually Viz above, 2000 AD or whatever Judge Dredd was in. A more amusing one might have been when random police types got to wander into schools and tell us of the dangers of power lines, train tracks and whatever else. The video they had opted for the "left to the imagination approach" which my 7 year old self promptly declared bullshit over as random medical shows that were on during primetime Saturday night would show full gore and everything. I was also a veteran of woundcare magazines (sadly image search is not even close to the fun of those) but that is a different discussion. Still first time you noticed it in films/TV, cartoons, comics or otherwise?
