Guillermo Cantu, Jr

Instructor's Bio

Guillermo Cantu has been an active San Antonio police officer in San Antonio, TX for the past 22 yrs. while spending 17 yrs. of it assigned to the Special Weapons & Tactics unit. During this time with the S.W.A.T. team, "Willie" served as an entry team member in various positions of the lineup and eventually becoming one of the "team leaders". As a "team leader", Willie was responsible for reconnaissance and planning of numerous high risk warrants and critical incidents.

The last years of Willie's S.W.A.T. assignment was that of the team's "training coordinator" and he was responsible for overseeing the San Antonio S.W.A.T. unit's weekly training which included documentation, planning and instructing different aspects of the training curriculum. As an instructor, Willie trained the unit in firearms, chemical agents, less-lethal munitions, distraction devices, raid planning & entry training to name a few topics.

Willie's experience as a trainer has allowed him the privilege to be a regional training coordinator for the Texas Tactical Police Officers Association and board member. As an adjunct instructor for C.A.T.I. (Center for Advanced Tactical Immobilization), Willie has traveled to numerous parts of Brasil to train the countries' civil, municipal, state and federal police. The State Department contracted Willie to travel to various parts of Mexico and train the countries' civil, municipal, state & federal police departments. He was also tasked with coordinating and training detectives of the S.A.P.D.'s R.O.P. and Narcotics units, as well as officers of T.R.U. and S.A.F.F.E. units. Because of these numerous contacts, Willie and Off. Joe Obregon of the S.W.A.T. unit held courses for the Secret Service task force of San Antonio, Baytown P.D. & Fair Oaks Ranch P.D. Currently, Willie is assigned to the Repeat Offenders Program "R.O.P.", is an instructor for the San Antonio College Basic Peace Officer Academy - Phase III tactics, and is contracted by the S. TX H.I.D.T.A. group for training H.I.D.T.A. task forces in TX.

The aforementioned accomplishments have only reinforced Willie's passion for training law enforcement officers and it has come to the creation of "Street Sense Tactical Training". The goal of the company is to provide quality training of various topics of tactics at an affordable rate that allow officers to fit into their budget. The tactics taught are tailored from past training courses attended as a student, experiences training other students of all levels, operational experience and historical warfare.

Tactics courses can be tailored for any department's goals with an aim to make each course as realistic as possible and targeting "real life" experiences.

Tactical Tip of the Week


As police officers conduct a stop of a vehicle during their duties, the legal reasons that authorize an officer to conduct the stop vary from traffic infractions to immediate arrest. Most legal reasons are for traffic violations committed by daily drivers as officers strive to keep the streets & highways safe. These traffic stops are considered "routine" because most of the interactions result as more of a "customer/employee" interaction than an enforcement of law.

When an officer conducts several of these "routine" traffic stops daily, either as an officer assigned to the traffic unit or patrol officer & the contacts all appear as though they are customer service oriented, their tactics begin to lax due to their mentality of perceptual lack of danger. This is called complacency where both tactics & mentality stay in an easy common rythm expecting the same dangerless results. The obvious problem for an officer is knowing which stop will be the one that may be fatal to their life. 

Mentally "clean your slate" after your last stop or before your next. Remind yourself that the next vehicle is not the same vehicle & the next occupant or occupants are not the same people. The reason for the stop may or may not be the same but remember that the cause for the violation is most likely not the same; running late, evading or escaping something. Each stop requires equal amount of attention to its occupants & tactics.
