I dare say that the apparatchniki in our respective Totalitarian Governments are just itching to bill our relatives for the hollow-point bullets used to judicially execute us.
Taxing us for the time we spent in the cattle-car on the way to our deaths will just be another piece of their hellish wit.
OH, well then there were transportation costs as well, that are taxable. The gall of these sub-humans to do this.
