Seriously, screw them- I'm for equal protection under the law.
If ex-prison workers (or cops for that matter) get rights because of fear of criminals, than so should witnesses who testify in court, people who live in neighborhoods where crime happens, gas station attendants, liquor store owners, pizza deliverymen, (1) and anyone else who might be concerned about their safety.
(1) I just noticed that the people who I just pointed out have statistically more risky jobs than law enforcement.
