From what I have seen of this in various media today, he is very lucky not to be spending time at Her Majesties Pleasure. This idiot is behaving like lots of gamekeepers have over the years. While that doesn't excuse him, its the attitude of his employers that we should equally castigating today.
The last two paragraphs in the above BBC link speaks volumes ::
"The Stody Estate is now being investigated by the Rural Payments Agency which could withdraw tens of thousands of pounds of subsidies if the estate is found to have been negligent, prosecutor Kevin Eastwick said.
In a statement, the estate distanced itself from the offences saying it had considered Lambert a "valued and trusted member of staff" and that he was "not authorised, trained or asked to kill wildlife".
Weasel words if ever I heard them.
