I don't like the "dont draw within 30 feet" comment. I am not a LEO but a lot of the LEO training footage I have looked at on the interweb and such seems to show ways around a close advancing target; such as stepping back or using your "weak" arm to hold the suspect at bay for the few seconds it takes to get your gun out of the holster. Reaction time is also a big factor; while I doubt many of us are regular lone rangers unless the bad guy has zeroed in on you as a threat I highly doubt they will have the time to mentally process what is going on and close the distance of 30 feet in time to not get lit up.
