No need to be rude

From a news report on the trial of Ricardo Morrison, the son of a police officer, accused of murdering his girlfriend, Amy Leigh Barnes:

Ms Barnes's mother, Karyn, phoned Pc Wilks from the hospital soon after the attack.

"She told her that Amy had been stabbed and accused her son, Ricardo Morrison, of doing it," he said.

...

Pc Wilks then sent a text to Ms Barnes' mother: "I know what my son has done is unforgivable. No need to be rude. Now I understand more about your family.

"Do not call me again. My son will be dealt with by law."
