If one lives in a CSC state, then one can dispute and delete INQs in the same manner.
Fraud alert, schmaud alert. Got one on my account. Hasn't caused me any problems, other than not being able to get the wife signed up for a MyFico free trial. But once you've got a MyFico Scorewatch subscription, fraud alert won't hurt you. Besides, it drops in 90 days and you can write and get it removed.
Heard mixed things about INQs older than 12 months. Certainly carry less weight, but not entirely weightless.
