Karma it isn’t. Karma isn’t real and it sure isn’t a personality. Pay back is from God. Rom 12.19. You reap what you sow. Gal 6.7. Pro 26.27. Matt 26.51-52. Rev 13.10. There is a lot of killing and shootings in neighborhoods and that isn’t the police fault. Police do what they can with what they have. The problem is the person or persons out there shooting. This problem is individual has to be solved individually. Each person with a weapon must repent. Each person with a weapon must accept the gospel of Jesus Christ and allow the message of God to save them from their sins. Rom 1:14-17. Mark 1.15. Roman 10.8-15. Col 1.5. Isa 1.16-20. Each person with a weapon must realize that maiming or killing someone is a sin because it is murder and that isn’t following the golden rule. Matt 5.21. Matt 7.12. 1 Pt 3.10. Gal 5.14. The way to stop the killing is stop sinning. We are now paying the price for human behavior to exist and not believe in God or His holy word. Man does as he pleases and if that means killing someone then so be it. Jer 16.12.
There has been a lot of good people killed in the violence; but I also believe that some of the dead were criminals and they simply reaped what they had sown.
