I have never heard of this web site before, so I don't know what its editorial practices are.

However, as I read the story, it seemed fake to me. Its supposed to be a first hand account from a Mexican cop of some sort. Yet it is written in colloquial American English. Do you really think a mexican cop would tell his story in American English?

It even has common mistakes that you see Americans make pretty regularly like transposing the 'r' and 'o' in "from" to get "form".
