Good post and thanks for thinking of me.
I am not really up on the lastest light info, but guessing your son got a Streamlight Stinger 2020? Those seem to be the benchmark in law enforcement. I still have and use my Streamlight Pro-Tac HPL (USB rechargeable) a lot here at home and on the road. Druff happened to buy the same light a well. I assume he used it during his recently black out. Mark my words, your son will be using his flashlight a lot on the job. As for handcuffs, I know S&W is a good brand. As a park ranger, he might actually use them on someone. Hope you can keep us updated on his progress.
As for law enforcement, if I was going to get into it, I would love to be a LE Ranger for the Department of the Interior, a federal job. They have large areas to patrol of federal land and not always doing the routine city police duties.
Here is a picture of a protest in Nevada (possible Nye County) about 4-5 years ago. The officers are Dept of Interior Rangers, full fledged federal law enforcement. Seems like a pretty good gig.
Side note- This is why I enjoy bulletin board forums like this- information sharing.
