Don't think it's a bad area, especially the area toward the end of 15…
Mostly of the things that do happen probably in the middle of MM blvd, and are more petty crime, like people ripping of acura/honda badges from cars, occasional burglarly if you leave your garage doors open,etc. But probably not at that end of MM, and it doesn't happen that often. Again, this was what friends that live in MM told me.
I did hear one of my spouses coworkers was held up at gunpoint in her apartment complex last year as she was parking her car. I think it was that complex near the LA Fitness Center (can't think of the name anymore). But it was pretty random, and no one go hurt.
