Headlines: House owner arrested after yob urinating against his house is stabbed to death
Now I read it as "An old lonely guy goes postal after being tormented by yobs", obviously the other take on it is "Young lad has life cruelly snatched away for shennanigans"
How do you read this story?
To be fair to the Daily mail, I think they have left it open for either....
PH comments please.
