He didn't. He attempted to have people assassinated but it was a sting operation and the images of the hits were faked.
Wait, how do we know it was fake ? Can you point to some link where I can read about it ?
Even I was under the impression, it was all real.
Because the police said they faked them. There's even chat logs of conversations between the would-be hitman and dpr where he gets shown the pictures and he comments on them.
