For foreigners calling the police

Quote from post:

"I've lived here 16 years and have called the police numerous times. I certainly wasn't bitchy. Actually I was quite polite. I do know that there are reglamentos regarding the level of the noise allowed in the El Centro area. This from people who work in reglamentos in the city. My husband called the police again, and the noise was curtailed yesterday.

In a post further down you suggested that people who read this board, who are most likely foreigners, call the police if they have an issue, and then you basically told me it was useless to call if you're a "foreigner". So, what is the real story...???"

Hello jr:
Same as you, I have over 16 years here as a permanent resident......
My experience is, generally speaking, the supposed police, called "policía preventíva", 11 times out of 10, are useless in resolving complaints about these types of issues.
Although recently on Dec. 5 2015, between shortly after 1 a.m., and finalizing with a THIRD call at 2 a.m., my noise problem complaint was taken care of. So, it is not impossible.
I would add, besides Rob's suggestions on "how to", be persistent, firm, yet polite, adding a "muchas gracias" at the conclusion of your dialog.
I have also noted that, most of the complaining is done by us "bitchy foreigners".
It seems though, that the local resident Mexican population, do NOT do much complaining about these civil conduct issues, they just either are used to it, adapt to it, or just shrug it off. Probably not worth their time and energy, and maybe an expense in complaining, pórque, ya saben, que, los policías NO HACEN NADA.
