You have to love assholes like the guy who wrote that letter.
"it has been bothering me for months"... but did he go talk to Joe.. I doubt it.
"we have underage daughters who live in the neighborhood". How is this relivent unless your kids trespass and break into Joe's house while he is filming, or are you trying to imply people who shoot porn are child molestors and he is likely to kidnap your child or try to lure them into some cp stuff ?
" what he is doing is illegal" ( in regards to opperating with out a business license and doing business out of a residence). Strong words "doing somethign illegal" for possibly not having a business license, usually "doing something illegal you think dealing drugs, or worse. Simply runing a business out of your home isn't illegal, a lot of people have a home based business these days.
People like this kill me, I wonder if he is really stupid and believes what he is saying or if he is just trying to sensationalize it to get everyone else fired up, and the main reason he is mad is because joe called animial control because of the guys dog. The guy's dog is likely more a risk to the young children in the neighborhood then Joe.
