Elements of organized crime have used a very effective way to slow down the movement of military forces when attemting to halt sicarios from causing mayhem in cities in the states of Nuevo Leon and Tamaulipas. These sicarios have been conducting "narcobloqueos" or "street blockades" to impede the military from reaching some of the shootouts in the cities.
It has been interesting how some of these operatives are able to conduct numerous blockades in the middle of the cities, carjacking big trucks, tractors, buses and regular motorists, to use their vehicles to block main roadways. They use high caliber weapons to take the keys from motorists and use their vehicles as obstacles to block the streets.
How do they get away with such blatant acts?
Here is a video from Televisa where a camera captured heavily armed sicarios highjacking vehicles and blocking a road and, guess what? A state police unit arrives, they see the armed sicarios, who make no attempt to flee, and the police drive away very fast.
Where they afraid to confront the sicarios, or where they accomplices?
It's one or the other, rest assured.
