Who should have the burden of proof?

• To sort things out, the one who is messing it all up in the first place should have the burden of proof.
• In an interaction, the one who is acting and not the one who is responding should have the burden of proof.
• Organizations vs individuals, given a hazardous condition, the former should have the burden of proof. But individuals must use their judgment to protect themselves.

In the end, do justly the best you can and keep course correcting. Remember what Dylan said:

All the truth in the world adds up to one big lie.
