In most cases, once you have put the (new) safeguards in place then a prosecution is unlikely to be the appropriate response. To that extent, therefore, it is to make it less likely that these cases will be prosecuted.
In summary, there is a clear distinction between four types of case: the first three to be robustly prosecuted, the fourth (offensive messages) to be treated very differently.
– Director of Public Prosecutions Keir Starmer QC
The fourth one is probably there where the more difficult decisions have been in recent months and certainly where there's been a growth in decisions. There we've put in a double safeguard: high threshold and unlikely to be in the public interest.
It doesn't mean no cases but it certainly puts in that double safeguard before a case is brought.
