Warning shots? As many of the bad reasons for so doing have been mentioned, I won’t belabor the point.
Are you willing to waste a life-saving shot, risk a malfunction, use up to perhaps 20% of your available ammo, be responsible for every inch of the shot’s trajectory and everything in its path?
Having firearm in hand before it is actually needed for discharge, but not prior to being fully justified in presenting it is a fine line that needs to be fully considered. Either way, you may be in trouble or dead.
Finally, the situation is critical to understanding this paradigm. In ones house? No need to keep holstered it’s your domain, on the street in public places? Holstered until just before it is required to be employed.
Those who describe having used warning shots ought to be a bit more descriptive. In a military context I have used warning shots ( secure facility overseas) followed with lethal fire and in life as a US resident, I have used a sidearm in what thankfully ended w/o shots being fired.
No situation is so textbook that anyone of us can or ought to expect a certain set of lockstep reactions. As those who have been in such situations can attest to, nothing makes a whole lot of rational sense until it is over and you are still breathing.
Whatever you do, indeed do take the advice to have a well-rehearsed statement for the police. Make it short, sweet and easily repeatable- then say it over and over until your attorney advises you further.
Be safe, trust God.
Even Joe Biden recommends firing warning shots, what other authority do you need? (sarc)
