Legacy Health increased security measures at its hospitals after the fatal shooting of Mr. Smallwood. This included installing metal detectors with bag search at every system hospital, installing bullet-slow film on hospital main entrances and emergency departments and on glass in internal entrances.

The parents of Bobby Smallwood, the security guard shot and killed last year at Legacy Good Samaritan Medical Center, sued the hospital Monday, arguing that it put their son in mortal danger by failing to enforce basic workplace violence prevention protocols.
