It says 26,000 members of the armed services are ESTIMATED to have been sexually assaulted....
I heard yesterday that the actual number of reported cases of sexual assault was around 3,000. So it is estimated that 7.5 times the reported assaults didn’t take time to report it. For sure there are some cases that don’t get reported but the multiplier to the actual number is just a number pulled from thin air.
I’m thinking that your thinking is correct.
