Sorry this is so long, but it is the definition in law of incitement
Incitement is a specific crime.
Quote - "Incitement was an offence under the common law of England and Wales. It consisted of persuading, encouraging, instigating, pressuring, or threatening so as to cause another to commit a crime.
It was abolished in England and Wales on 1 October 2008 when Part 2 of the Serious Crime Act 2007 came into force, replacing it with three new statutory offences of encouraging or assisting crime."
"Encouraging or assisting a crime is itself a crime in English law. The . . . requirement is that the defendant carry out an act capable of "encouraging or assisting" the commission of another offence. An offence is committed under section 44, if this is done with intent to do the same; under section 45 if it is done "believing that the offence will be committed and that the act will encourage or assist its commission"; or under section 46 where there are multiple possible offences being encouraged or assisted, and at least one is foreseen.
Whereas incitement can only be committed when the defendant incites the principal offender, the crime of "encouraging or assisting" includes helping an accessory.
Offences under Sections 45 and 46 are only committed if the defendant believes that both the crime will be committed, and that the act will encourage or assist the offender: that they might do so is not enough. . . it is necessary that the defendant intend or be reckless to any required circumstances or consequences – for example, that death was a result.
