Yes - Based on what we're being told, either Jussie or somebody in his circle wasn't being truthful or was misinformed, TMZ is spreading ******** again or the cops got the report wrong. Each raises its own problems.
No, it doesn't.
Again I'm basing this solely on my personal experiences but there is a possibility that it could've happened just as it's been described. Jussie's attackers aren't seen entering, around or leaving the scene and there's a 60 second blind spot. It is absolutely possible to be attacked that quickly because it's happened to me more than once. Walking down the street, turn the corner, I'm suddenly in a fight and as quickly as it started, he's gone. Very unnerving.
For his account to be true if this attack occurred in the blind spot, it's possible his attackers were loitering there to begin with, attacked him and fled into a nearby building or structure not covered by cameras. They didn't necessarily have to flea the area.
Note that in the police report Jussie does not know which way his attackers fled so this scenario must be considered as well.
