I believe the constitution holds that everyone is entitled to a defense.
Rich or poor. "Good" or "bad". Popular or unpopular.
The day that one group is allowed to deny the rights of any other group is reminiscent of how Nazi Germany got its start....
I'm sure you have heard Niemöller's quotation that begins with.....

"First they came for the Socialists, and I did not speak out—
Because I was not a Socialist...."

Just substitute your favorite group you want to deny rights to and you're starting down the same road of the Nazis...
