Your last sentence seems to contradict your first, whereas what you would really prefer is to disarm the police. Sadly I don't think that's so practical, in the same way that it would be impractical for US police to go unarmed given the high incidence of gun ownership in the US. I grew up in a country where police are
not normally armed (other than with a small baton or similar personal defense weapon) and much prefer that, but when there's a lot of weapons around that's a reality you have to deal with.
As regards these cyberattacks, the NSA is at fault for its poor security allowing the weapons to become available to bad actors, but the mere existence or stockpiling of weapons is not the direct cause of crime. It might be more useful right now to consider who is operating these weapons, where they are firing them from, and how best to neutralize them.
tl;dr when you're under fire is not the time to worry about gun control.
