Yes, American police use these kinds of justifications when innocent people are killed too. It's absurd (watch Surviving Edged Weapons [0] some time) either way.
The reality is, if you have soldiers mowing down children throwing rocks, mowing down families driving around, mowing down kids playing football, mowing down toddlers in their bedrooms, mowing down hundreds of people each year [1], you've over-indexed on vigilance and under-indexed on the value of human life. You're not trigger-ready, you're trigger-happy.
