Ouja so should have been dead before Knight ever got the chance to steal a car and pick him up. If this was realistic those cops would have shot him full of holes the minute he punched out the first cop and ran, instead of just walking around waving their guns with threats that were obviously empty by that point.
Ryuki's cops are a joke.
Speaking of guns, where the hell did he pick up that handcannon he had when he had all those people hostage? I didn't see any cops carrying a gun that big, and in Japan it's illegal for civilians to own guns at all!
It's possible he has connections (he was able to afford Super Lawyer for his trial, after all), but it'd be good to have that kind of thing established NOW instead of later, if at all.
