Anyone have troubles with break-ins?

Before my 6 got totalled, my car got broken into twice in 2.5 weeks and I caught someone about to break in a 3rd time a week after. What I found weird is that there are 5 other Mazdas in the same parking lot (Mazda 3, 6, and CX-9’s) yet mine was being targetted.

I’m just asking to see if anyone else experienced this, or just myself? And do these cars have any anti-theft systems in place other than an immobilizer?

(This is not a jab at Mazda 6 / Atenza or the Mazda community, I still liked my ownership of the ‘13 Mazda 6, V6)
