Speech isn't violence because its nothing more than words and our speech is a protected right. Offering money to murder someone is almost certainly illegal because they are doing more than talking, they are choosing to collude in the act of murder and a jury is much more likely to agree there.

My point wasn't that money had to change hands or be offered, I was responding to an earlier comment. A person directly taking part in plotting to commit murder I'd also likely breaking the law and likely to lose a jury trial if they are actively plotting a murder whether money I'd involved or not. Saying "someone should" simply isn't a plot.
