Advice on how to liquidate system

Yeah man, that’s all pending. A flash-bang detonated right near my head during on the job training (ear pro wasn’t mandated). 

That one sentence stuck with me all this time so I looked up anything on flash bang grenade training and found this 17 yr old article on a police site on the use and extreme dangers of flash bang grenades.

This one passage caught my attention:

• Avoid looking directly at the suspect when releasing the device: This almost always causes the device to be thrown closer to the suspect than the suggested five feet, due to the "pitch and catch" process we have subconsciously practiced since childhood. Officers should instead focus on the floor 45 degrees to the side, and 5 feet away from the suspect. 

These devices go off at 160-180 decibels!  I know the article is an old one but if anything, common sense progress has to have been made by then. If they had you laying on the floor and just tossed it near you and some other guys as a way of preconditioning you to the effects, I'd get a lawyer as they're not qualified trainers in the least. That, and not requiring ear protection with that loud an event is completely unprofessional. 

All the best,

I would wait for a good long time before sending off your system. Back in the day I was messing around with the youngsters and got slapped right upside my head and like you, I thought my eardrum popped. Couldn't hear straight for the longest time and like you, the tinnitus was bad. Muffled sound and with my balance off a bit, I thought I was a goner. 

Time did heal everything and it didn't take that long, relatively speaking. 

All the best,
