England riots: Unease over 'too harsh' sentences
Tough prison sentences for those involved in riots have been criticised as "disproportionate".
One man jailed for four years for inciting unrest on Facebook said he will appeal.
Lawyers and campaigners warned that the rush to send out a tough message and to make an example of those involved in violence was leading to "some very bad sentences".
The call came after Jordan Blackshaw (20) and Perry Sutcliffe-Keenan (22) were jailed for each setting up Facebook pages that encouraged people to riot. Even though no disorder occurred they were given four years each.
Blackshaw's solicitor Chris Johnson said his family was "shocked and upset" at the sentence and said he had been instructed to appeal against it.
Prime Minister David Cameron defended the punishment, saying: "What happened on our streets was absolutely appalling behaviour and to send a very clear message that it's wrong and won't be tolerated is what the criminal justice system should be doing."
However, senior Liberal Democrats, lawyers and human rights campaigners urged caution. Former party leader Sir Menzies Campbell said: "With all due deference, politicians should not be cheering nor booing in the matter of sentencing.
"It is an important part of our constitutional principles that political influence is not directed at the judicial system."
Leading criminal barrister John Cooper QC warned that judges and magistrates had a duty "not to be influenced by angry Britain", describing some of the sentences handed down as "disproportionate and somewhat hysterical".
Sally Ireland, director of criminal justice policy at the Justice campaign group, also said several cases appeared "outside the normal range", adding that giving rioters disproportionate sentences could "compromise confidence in the justice system".
