Don't hire for less!
Are the security companies you hire doing enough when it comes to making sure it's employees are trained and properly confident when dealing with stressful situations especially those that involve armed officers and firearms? Don't be so quick when hiring a agency to handle security situations. Shop around and make sure to check there hystory of suits and incidents involving their staff. Remember, just because they cost the least does not mean they are doing the best. If you want good quality service be prepared the pay for it. It may save you or your company the "Big headache" in the end.
