Dude, you're high on my list of good guys.Our current policy and training says that if you are the only officer on scene and shots are being fired, you go in period. If it involves driving through a door to make entry, do what you have to do. There is a fine line with this type of situation. You do not want to go rushing in to a barricaded subject but yet you had better not be standing around outside waiting while people are actively being killed. I understand that the ERT/SWAT training and mindset is somewhat different.
