I live in ciudad juarez and i see this type of things everyday, it's a shame that our autorities are corrupted by drug cartels, the only ones that are fighting back are the mexican army.
This drug war has been since 2008 and a lot of business have closed here in Juarez, streets are empty after 9:00 pm and you can hear gunshots anytime of the day.
I remember when i was in highschool on the corner of the street there was a dead man with a pig face, and i remember that my friends have just got used to the violence here and we were just like, oh look there's another one..... i have a photo but i can't find it...... i'll upload it
