But as mentioned before, won't those looking to cause harm still cause harm in another fashion?

Does that justify giving them what they need to cause harm anyways? I don't think so. Plan A is always the most ruthless for those looking to do damage. Cut off access to the necessities for Plan A, force the execution of Plan B, and save some lives in the process.
