I think it looks like a normal venn diagram. Some things are similar and some different and it depends on what deployments or forces each has worked on. That's why NG troops are getting extra training in police duties and working together with normal police.
Police training academy is already generally considered to be insufficient, which is part of why cops continue to receive so much ongoing training as part of the job.
Getting a few rushed bootcamp style classes is not going to do anything to remotely bridge that gap.
