The scenario was (in your original post) that the perp' was guilty. You asked about stiffer sentences.You have invented a scenario of being guilty of causing a riot and are now trying to fit it in to the offence of rioting.
A police officer assaults an innocent black man due to mistaken identity, the outrage causes a riot.
A politician makes a provocative speech which triggers a protest. The protest turns in to a riot.
A journalist incorrectly reports on a story which causes public anger which turns in to a riot.
All 3 have caused a riot. None are guilty of sec 1 public order - rioting.
So on that basis I asked you a yes/no question in a similar capacity, to which you floundered and waffled.
The perp is guilty of inciting a riot. Should they be jailed? Yes/no?
It really is not that difficult (to play your game) boyo.
