W: Dade County, Florida is a dangerous place to be these days, according to a Miami Herald poll released this week. [6] The survey reports that 42% of people interviewed or their family members have been victims of burglary, robbery or assault in the past 5 years. Almost one half say they need guns to feel safe in Dade County. The Herald conducted the survey in the wake of a widely publicized booby trap killing, in which a store owner killed a would-be burglar. Herald reporter Andre Vicluchee has been covering the story.
M: [7] The one part that I think was a little surprising was the number of people who feel that it is okay to shoot, to kill an intruder that comes into your house. We found 63% feel that they should have the right to kill an intruder in their house.
W: Whether or not the person is armed or not only if...
M: Whether they know or not if the person is armed. It surprised us; we figured there would be something of a hard-line attitude out there. But this was probably above what we expected.
W: Well, it seems, though, that people are perceiving at least in Dade County that crimes are really in a bad situation that they are willing to do something about it with violence.
M: Yes. I went back and questioned more at length another 15 or 20 respondents from the poll. And they all seem to feel that, if they find themselves in a situation in which they have to take some action, even if it means killing somebody, they’ll do it.
W: [8] I’ll take it that Miami Herald poll and perhaps that a lot of people’s feelings about crimes stem in part from this case of the booby trap victim, a store owner booby trapped his variety store raider in a black neighborhood. Tell us about that case.
M: The man’s name is Prentice Raschid. He is a black business man who has a small store in a black high-crime area of town. [9] He has been burglarized, I think, 7 or 8 times over the past few weeks, had asked for help from the police and had not gotten any answer to his satisfaction. So he went ahead and set up an electric booby trap in the store. About a week and a half ago one morning, they found a young man dead in the booby trap who had been electrocuted while trying to carry out some stuff from the store.
W: And what has the public reaction been then?
M: The public reaction has been an overwhelming support for Mr. Raschid. [10] He has been charged with manslaughter, and with setting up an illegal man trap.
