When was the last time you practiced drawing from concealed. Watch this Surveillance video of an off-duty sheriff's officer shooting of a robbery suspect in Chicago. Notice how fast the three suspects approached the man. Luckily he had his gun on him not inside the car. Pay attention to how fast after he draws his gun he is on target and delivering a lethal shot to the robber. Then he goes to the passenger side of the car retrieves a cell phone and calls 911. He still has his gun drawn and looking for more threats.
