Man of Honour
All these armchair IT wizards saying “omfg how do you mistake a gun for a taser, incompetent idiots!?“ need to just pipe down. The hardest decision they have to make every day is whether to have soy or almond milk with their coffee.
If someone trained with and routinely carrying both a gun and a taser can mistake one for the other then one of those objects is designed incorrectly, their training is inadequate or they aren't at a high enough level of competence. Or a combination of the above. When the consequences of a mistake are a matter of life and death, adequate steps should be constantly in place to prevent that mistake.
They're often not, though. I watch a Youtube channel ("Plainly Difficult") that has short documentaries on various failures, often fatal and sometimes disastrous. Reactor meltdowns, criticality events, dam failures, etc. The prevailing theme is that adequate steps were not taken.
