There is still slavery in the world, sad to say, so yes people can finds way to justify just about anything.
Well luckily I'm at the "lie back and enjoy life" stage of life myself - and it's great! But it doesn't mean I don't do other things, like volunteer work or help with charity gambling nights and such here and there.
And I'm right with you on that punishment for someone who willfully attempts to overthrow America and all it stands for, shitting on the constitution and believing their rights are more important than those of anyone else. The killing of that police officer was unimaginably horrific - what won't such people stop at? To me, it cries out for institutionalization of that person for the duration of their life, it's just too dangerous to let such violent people roam around free.
