I think Christine Dean should be the one facing the outcry & not Mr Molloy, her performance in the Court far outstripped her remit. As to these 2 youths they deserved their epithet & more, furthermore the "Parents" should be ashamed of themselves & the neglect they have shown their offspring by not instilling basic tenets of decency, politeness & acceptable standards of social behaviour. A truly poor example of modern day Britain.
As to writing a letter, I wonder if e-mail is acceptable ?
