How I miss my fenceless, wall-less, everything less home in California.
I understand the desire to protect one's family and self from criminal actions, not only in Brazil but in all Latin American countries, by installing barbed wires, electric fences, bars and huge walls, but I feel the need for feeling safe simply because, if needed, the law defenders will be at my door within a few minutes after I call 911.
I live in São Paulo in a house with low walls, no gadgets and no fences or bars. Of course we lock doors (not that naïve), but perhaps miraculously, our house hasn't been breached yet.
I have neighbors that, to my right, have a 10 foot wall with electric wires in top. To my left a neighbor has 8 feet high bars which a criminal could jump over in 15 seconds. Further to my left, the next neighbor used to have a fence but has now been building a wall, around 9 footer, in a time frame that in the US I could have built an entire house. The cost is probably the same as the house I could have built in the US.
I can't believe these barriers will do much to protect, other than the illusion of protection. Nothing can be as effective as an effective police force.
