That same type of outcome is happening across the USA and Canada as a result of the uncontrolled walk-ins taking up residence.
More bad acts will happen, IMHO.
This Russian thing is worse, these were the hardened criminals already in prison, then taken out, trained to operate as a team, trained to use and live with true weapons of war and the proper implementation of them, and trained to think and act at the ultimate heights of violence, actual war, against professional soldiers.
Individual violence isn’t the big threat or the long-term threat, some sociopath shooting an old lady is nothing new whether he is called ex-Wagner or not.
Over time as the more intelligent and serious war-veteran Wagner men find each other and gravitate to each other and are hired by established criminal organizations crime in Russia will reach a new level and larger, more sophisticated crimes will be conducted by professionals.
