The crime of self-solicitation

I hold that we could justifiably criminalize some threats, on account of the fact that issuing them renders one more likely to commit a crime. But I also point out that if we criminalize some threat-issuing, we will de facto criminalize some warning-issuing, which is unjust. So we ought not to criminalize any threat-issuing. Instead, we should criminalize (roughly) rendering oneself more likely to commit a crime. This would allow us to punish all the threat-issuers we should want to punish. It would also force us to punish some warning-issuers, but we would not be punishing them for their warning-issuing.
