Well, if you can't beat 'em, join 'em!
What do Liverpool plod have to say for themselves?
"Several enquiries were made to find an organisation who could assist with recovering the deer safely, but unfortunately we were unable to get assistance and as the hours went by the deer became more distressed.
"There was no option to let the deer wander as it could be a danger to motorists and members of the public in the area, particularly as the hours of darkness approached.
"As a result a decision was made in the early evening to euthanise the deer."
Let's hope The Deer Hunter is on duty the next time Scouse dogs pose 'a danger', eh?
