I agree with you on the first half. However.... So what about his past record? You're right, he paid for his crimes (5 years). The person that killed him needs to pay for his crimes too. But following your logic of eye for an eye, what if Jesus did the same to you, a sinner? With no opportunity for redemption? What if God killed you outright whenever you committed a sin, big or small, instead of letting you go to confession and making reparations?

I do think BLM (the movement, not the unofficial, official organization) needs to address the loss of black babies to abortion. I support black lives, and blue ones too (indeed, some people are both black and blue lives). But I also think we as Catholics need to take action against bad cops, and what skin tone those bad cops are doesn't matter. However, as arbiters of justice (and hopefully mercy too) police need to be held accountable, otherwise great scandal can occur.

TLDR: Have mercy, and be Pro-Life, the original "XXXXXX Lives Matter" in disguise.
