I am "sure" they plan to have security no matter where they are located, but this area may or may not directly across from La Union. Criminals don't need to live directly across from where they rob. Frequently they don't.
So true windeguy, thieves often commute to "work".
But seems the thieves in DR also forget to follow the old rule of "Don't sh*t where you eat".
I've come to know a lot of good people (with jobs) who live in La Union and are not thieves.
