Booby Traps = Justified?

In a 2-3 page essay, please write a paper discussing this issue (remember to use at least 3 APA citations/references throughout your paper, give credit where credit is due!)

Contrary to common law, today, in most, if not all states, a person cannot use deadly force in the defense of their property.

Do you agree with this challenge?

Should a property owner be allowed to use a bobby trap as long as notice, by use of sign for example, is provided to an intruder?

Please provide a legal analysis and the case law, use both within your analysis to support your argument.
