Old Pete Wogan (retired Columbus Ohio LEO) used to tell the story that I think sums up the bully/bully beater scenario.
This woman was on her husbands case like green on celery, 24/7/365, . . . and for any reason she could think of or use.
Pete and his partner went there for the unteenth time, . . . and because he had shoved her, . . . they were taking him downtown. Leaving, . . . he told her he'd be back, . . . and when he came back, . . . her days on this world were ended.
She jumped into her usual tirade, . . . that was only ended when Pete told her to shut up. Hubby never made another sound till they go to the door and he remarked: "Just remember woman, . . . I'll get out of that jail a heck of a lot sooner than you'll get out of the grave".
It doesn't justify shooting the bully or anything, . . . but sometimes I really think that there are people who get that mind set, . . . and the next thing you know, . . . there's another body to take care of.
May God bless,
Dwight
