Where you live ain't shit AA61hvy and I do have to admit I am a bit surprised that what happened, happened. The neighborhood you are in has cleaned up quite a bit from what it was 5-7 years ago. You have quite a bit of overlapping police coverage, you have UD campus cops, you have the Jokewood(Oakwood) PD
patrolling one perimiter of the campus and I have even seen them as far down as the UDF on Brown street, and if you ever see them at night since their budget cuts, the Dayton PD
Maybe the cleanup is part of the problem, the area isn't patrolled as much as it was at one point in time.
A pasty white boy like you needs to try standing on the corner of Third and Gettysburg some night and see how long it takes to get shot, same thing if you go North of downtown, or East and visit the mullet crowd. For best results go after midnight and dress nicely.
Im serious though, don't walk alone, that is just kind of common sense, it doesn't matter how big you are if the guy comes up behind you with some sort of weapon. However, if he sees two or more of you he will move on to an easier target, criminals like that are pussies, they don't want a fight. You also don't have to come right out and say "hey I don't wanna get jumped, will you walk home with me?" but given the present situation I don't think anyone would make fun of you. Everyone is going to go home at some point, just go with the group.
Actually it is pretty smart of the crack head to work that area, UD isn't a cheap school and in all honesty a lot of college aged people lack situational awareness, especially if they are coming out of a bar. The leaving the bar part was the attackers mistake, in picking an easier target he also picked one that had just spent his money. Your friend was smart to not be carrying too much of value, maybe the dirtbag that attacked him will seek greener pastures if he keeps getting nothing but cell phones and empty wallets.
Things were better when it was two guys in a dorm room.
