I seemed to have not conveyed what bothered me about the topic. Essentially the article states that a wave of crime awaits yet several previous articles stated that a big majority of the prisioners were killed. People fleeing were also said to have been shot and given the kind of gruesome tactics, being wounded would be life changing.

During the autumn and winter clashes at Bakhmut, the Wagner Group suffered huge losses. It is estimated that out of approximately 50,000 prisoners recruited in the second half of 2022, only about 10,000 continued their service at the end of January; the rest had been killed, wounded or deserted.>

That was the situation in January, they took Bakhmut in May (with the battle getting much worse during the end). Given those numbers, I doubt that a wave of crime as stated seems realistic.
