What if I trip and fall and my hand holding money, eagerly trying to find some object to grab hold of to prevent my falls, snags your pocket, instantly consumnig all money within my hand as I fall briskly to the floor. You, sensing the sudden increase in mass of your pocket, beging to hastily make your escape leaving your precious and irreplacable magazine on the table next to where I fell. Me, now getting up, discovers, purely coincidently, a lone high cap magazine on the table. I, trying to do the right thing, spend an unmeasurable amount of time searching for the proper owner, but with no persons around I was forced to take it home to prevent it from being used illegaly in a crime. At that point I stored it with my other gun related items, locked away safetly to prevent children from accessing it, the whole time searching for the proper owner. I further know that the best way to find the owner is to take it out publicly, but I can't do that anywhere because of California's laws, so I take it to every range I go to and use it everytime I use my rifle so when the proper owner does see it, they will recognize it and ask for it back.
I don't see anything wrong with that...
