When a person has a wall, or a security gate, an attack dog, etc protecting their home.....this is incredibly offensive to your neighbors. Its like saying you think they are fucking criminals. The majority of people that would ever break in to your house are probably really struggling to survive. This "home protection" bullshit is just an excuse to be racist.
How do you know the neighbors find it offensive? By your reasoning (which is fucked) installing a backyard fence would also be offensive. Anyway, many cities, such as the one I live in, have restrictions regarding fencing. Code says a backyard fence is limited to 6' in height. Any property line fencing beyond the front facade of a home is limited to 3'. The construction side (good side) must be on the inside of the fence. Further restrictions may be added with the neighborhood association's requirements.
Our gated neighborhoods are more about symbolism than security. You may not be able to drive into these neighborhoods, but you can walk in on the sidewalks if you want to.
There are also laws regarding dogs. You may have up to four dogs.
Frequent or continuing noise for a period of 15 minutes in any hour emitted by an animal for which a person is responsible, except for animals provoked by a person trespassing, threatening to trespass, or unambiguously taunting the animal. You may be cited to appear in court and fined up to $500.00 per violation. Chronic violations may encourage the judge to order your dog to be removed from the City of West Linn.If you're suggesting installing a home security system is racist, you are completely out of touch with reality. But then, you think MJ was an innocent 'Peter Pan' when he took prepubescent boys (only boys) into his bed.
