Starting with "Well," suggests it somehow negates my point though.
I think "Also" would be more appropriate, which kind of acknowledges the problems in other countries I cited while also pointing out very real weaknesses in America's justice system.
This might seem pedantic, but the common reply I see to "this country does bad stuff" reduces to "well this country does bad stuff too!" It's not a productive argument because it tries to deflect attention and normalize the actions in question. Instead, we should be focusing on how to address all of these issues, because they definitely exist.
