I support the death penalty.
Violent robbers, murderers, rapist, terrorists, anyone who helps terrorists in any way - funding, information, logistics etc. should be put to death as soon as soon as they are done with their appeals! Not feeding criminals who have exhausted their appeals!!!
Making the executions public would be welcome starting with terrorists and their sympathisers!
Never count on making a good sale. Have the purchase price be so attractive that even a mediocre sale gives good returns.
