Seriously this planets going to hell, people have the moral thought pattern of the horned one himself.
No, the horned one himself would've stabbed Powell in the face and walked off with the phone, before he made chili out of Powell's family.
A robber would've held up a gun and said gimme your phone.
A thief would've snatched it from his pocket.
A finders=keepers type of person would've found the phone and said "yay, free cellphone!", slipped it in his pocket and made zip-nada-zero effort to return it.
Then there's this guy, who according to the Giz story asked around in the bar if someone had lost a phone, placed a few phone calls to various Apple numbers the following day, ended up talking to their support crew who dismissed him as a loon/prankster/fool. After that, he switched to finders-keepers mode.
One notch above him is a person more on top of things and with a better understanding of the law. While not quite prepared to immediately bend over backwards and make the return of the phone his life mission, said person would still have tried a little harder and come up with more ideas on how to return the phone, and turned it in to the police if said ideas turned out to be dead ends.
Finally there's goody-two-shoes scoutmaster who would've shot like a cannon out through the bar doors, run like Usain Bolt down to the police station, slapped the phone on the desk and asked for a cookie, and later called his mom and told her all about the heroic deed.
On a scale from 1 to 10 the finder is maybe a 4, pretty weak but certainly not at the bottom of the barrel of human filth. If the law rounds off 4 to zero and finds the defendant guilty of fencing and/or theft-by-whatever, that's fine by me, I respect that – I do however have little respect for binary-minded fascists who want to make this into the crime of the century and get a pants tent from imagining the finder of the phone in a prison dungeon. Not to mention hypocrites who act soooo surprised and shocked that everybody else isn't a 10 on this scale.
