I didn't survive Katrina there, but I did grow up out side there, worked there on and off, lived there for time and picked up a degree there. First, GO TO THE WWII MUSEUM and see the movie. Well, first bring a gun, then 2nd go to the museum. In some ways it is not as bad as it used to be, in others more so.
If you want, PM me and I'll give you some info. However, a significant number of cops will shake you down. Especially the black cops, especially the white cops....remember that. It's an equal opportunity town. Residents who have had their home broken into know better than to let a cop make a pass through the home unattended since additional things may go missing that way...but that happens pretty much everywhere....insurance is going to pay, you know.
Know two couples from Tulsa area went there and one of the women was talking on her cell in the French Quarter. Cop walked up, got rude and after a exchange back and forth he separated her from the others, threatened them and threatened her. Seems the cop told them she stole that telephone...don't backtalk or you're going to jail...this boy over here (about 10) said you stole his phone....no I did not, etc.... he pulled out club and said you're going to jail don't get smart with me...but, if you can work it out with the boy I will let you go...cop walks off 20 or so feet...boy walks up...says gimme $50 bitch....$50 comes out interchange over. Now, that's the fringe of the French Quarter where tourist frequent the heavily traveled parts don't get that and the mounted cops won't bother with that.
I can add a lot of other examples, but this encapsulates it. Lots of NOPD have ended up in jail over the years up to and including killing parents and burying them under the house and ambushing their partners then coming back to the scene of the crime...two notable cases but there are many more including drug rings, stolen car rings, etc. The stolen car ring has been busted at least twice I can remember...but still goes on...NO has a central place where the tow trucks bring them and then they are transported to chop shops if they want your car and no record of the tow will be found. Remember if you are in Metairie or Kenner you are in Jefferson Parish not Orleans and it is better...that's where the airport is. But, the airport is "New Orleans" property and they have some NOPD there.
The criminals...if they are young they might just kill you...oh yeah, if they are old they just might kill you too. If you are visited upon and you can't defend yourself, don't be belligerent and don't make eye contact unless you are doing the pleading thing to stay safe by telling them they how great they are and that they are "the man" and you are a pipsqueak or such. Do make eye contact before an exchange happens which will discourage you from being a target...just don't "stare them down" because that is an invitation.
If I were to defend myself there, and this is not advice to you or anyone else, I will .....if you want the rest you'll have to PM me. Since you are going to be in NO, if you happen to be there during voting, how about walking in and pulling the stick for the Repub for Lt. Gov.....
