Irregularities that really aren't
There have been a few comments made about how "Phoenix" is a little unrealistic, what with the cops all seeming to have New York/Jersey accents, and it raining a lot.
Well, having spent the majority of my life in Phoenix, AZ, I can tell you, there are a whole lot of former residents of New York and New Jersey in the Phoenix Police Department. Also, during late summer - when this movie is set - Phoenix enters the monsoon season, and approximately half of Phoenix's annual rainfall falls during this six week span.
Any other questions about irregularities in the movie, I'd be glad to help explain!
