Politifact has looked into Florida's use of their "Red Flag" legislation since Parkland 18 months ago.
With one stroke, Florida's legislature gave the gun grabbers exactly what they wanted. They have found that Florida executes Extreme Risk Protection Orders on average five times per day, with almost 2,500 confiscations in the last year:
It now appears that these laws are now being routinely used:
"Broward’s chief judge Jack Tuter said that when a law enforcement agency determines a person poses a threat to himself or others, the agency requests a risk protection order. "
"That works out to around five per day since the law took effect in March 2018.
Since then through July 2019, there were 2,396 risk protection orders issued by judges statewide. Counties with the highest number of orders were Polk (378), Pinellas (350), Broward (327), Volusia (173) and Miami-Dade (127)."
"Pinellas Sheriff Bob Gualtieri said in his county people surrendered about 700 firearms and over 135,000 rounds of ammunition."
If all these confiscated firearms were actually a danger to others, you would have thought that there would have been quite a few more "attacks" before these laws went into force, and that crime rates would have considerably dropped because of all the disarmed dangerous people. But this isn't what happened.
You can't prove a negative, but it's clear that these arms were not being used to threaten the public before they were confiscated.
Knowing that this is Florida, with a larger elderly population than many states, I'd wager that many of these firearms are being confiscated from older people that are not a threat to others, but who need the firearms for protection. If elderly abuse and crimes against aged citizens rise in Florida, you'll know why.
