You did the right thing( In acorner ) once at 4am i heard a woman getting her ribs cracked by her drunken boyfriend. I went and helped. Luckily for me some neighbours called police. When they came they told me I shouldn't have got involved. I felt ok up until they said that then I started shaking all over. He would have killed her if I hadnt gone to her. She was very drunk too and that maybe helped her not to feel his practising his martial arts on her....I never had any repercussions....and my husband never went to help despite his being a very strong man...so I commend you for following your instincts..or may I call them fellow feeling.This world is worse off when people turn a blind eye....luv Jjulia
