How about this, why don't you try having a civilized conversation? Read my comment in the entirety. Note I said The state law is very clear on the matter. He can build a outdoor range and use it as long as it isn't recklessly or negligently used. But I'd bet a dime to a donut that a good lawyer could show that any use as currently built would be in a negligent or reckless manner. And as the saying goes, any round leaving his property will have a lawyer attached to it. Now which would you rather see him spend his money on, a safe range or a lawsuit? I will also tell you this, some of those complaining are not his next door neighbors. They live in the neighborhood but not right next to him.
PS: I took the time to look at the location and per state, county, and city laws, that is a residential area with the primary purpose being a residence. I'll repeat the Florida law again so you can understand it with the pertinent info in red. Note, defensive use is legal.
Here is the info from the tax appraiser for use and lot size. In other words, a city lot size piece of property. That puts him clearly under the quoted statute. And to save you having to look up the 776.013 definition, it is: Those definitions were written in that section so as to provide the castle doctrine to the largest possible locations. It looks like the neighborhood is a near zero lot line property layout as the homes there are right next to the property lines to the side and rear of his property and his home is located right next to the rear and side lot lines. The fences you see in the video have houses right next to them. To the rear, he is shooting towards a home. To the front, he would be shooting towards a street and the home across from it.
