Tabbing order, accessibility.and guns

Two seperate questions from a paranoid advertiser

[vordmeister]

I lent a friend the mouse from the computer in the garage. The internet on that computer is now keyboard controlled. I've noticed when I tab down one of my pages the tabbing gets stuck in the Google ads and won't come out again.

Am I getting lost in the Iframe? Surely this is a bad thing for blind dudes and the like. Does Adsense pose an accessibility issue?

Second question while I'm posting. I have a page about life inside a Spitfire Squadron in WW2. No way am I promoting war, guns, or bombs but these things do get mentioned so I get PSAs. I'm reluctant to contact Google every time I get a problem in case they mark me down as troublesome. I'll remove the ads from that page.

How do you guys read the Adsense policies? Do you think I should contact Google to see if I can have this historical account on a site where other pages display Adsense?

About your second question: Taking the ad code off the page sounds sensible, since you're not going to get ads anyway, but I wouldn't worry about the rest of the site. Google wants to avoid being associated with gun sellers. If your site can't be confused with a seller's site (i.e., it's not an online gun store with history pages added on for flavor), you should be in no danger at all.
