Why do "American" cops "absolutely need" guns specifically in "low income areas"? You specifically said "low income", so I interpret that as meaning that you think that cops in high income areas don't need guns, but they do need them in low income areas, is that correct? Is this related to the idea that "low income areas" have higher crime? Do you also attribute it to the idea that "low income areas" have more dangerous violent people? Do you also believe that "low income areas" have higher rates of gun ownership/possession? Finally, can you describe what you mean by "low income areas"? In other words do you simply mean any municipality or neighborhood where the average income is below the local (city/state/national) mean/average? Or are there other characteristics you had in mind?Your normal "Everyday Cop" probably doesn't need a gun in a country that doesn't allow ordinary citizens to carry guns... A cop in an american low-income area though? Yeah, that guy absolutely needs a gun, and it's the expected outcome that sometimes bad people are shot to save innocent people.
Also, I'm assuming you said "American" because we allow gun ownership. Is that the only reason? In other words, do you take the position that any country that allows gun ownership should have their police force fully armed, or is there something else about America specifically that makes you favor armed police?
You said that " it's the expected outcome that sometimes bad people are shot to save innocent people"... I'm assuming that you are talking mostly about the police doing the shooting, since that's the topic... So do you also feel that it's the expected outcome that innocent people are shot unnecessarily? In other words, do you take the position that innocent people getting killed by the police is an OK exchange to give them the ability to kill bad people?
Kind of a tangent, but you also commented that in a place "that doesn't allow ordinary citizens to carry guns", the "normal "Everyday Cop" probably doesn't need a gun." Well, Chicago, and Washington D.C. for example had gun bans in place (that were eventually struck down by the Courts). Assuming those bans were still in place, did you have Chicago and D.C. in mind as the kinds of places where cops would not need guns? Or did you have a different kind of area/neighborhood in mind when you said that? In other words, if American cities had gun bans, would you support city cops going without guns?
