Bourbon at night is, in my opinion, no more dangerous than going to a bar. Sure someone might get drunk and make an ass out of themselves, but its pretty heavily patrolled by mounted cops, so it really doesn't get out of hand except during Mardi Gras. I generally advice people to not go during Mardi Gras as it's just pure chaos. Crim did a post from walking around Bourbon at night on her blog within the last 6 months, so that's probably like 4 or 5 posts back if you wanna see it, but that was during a festival, so it was more packed than what you'll probably see.
