> Why so sure he made a threat?

Sorry, ambiguous wording. I don't allege he called in a threat. Tesla publicly stated he made violent threats. The police refused to corroborate that claim. Tesla's statement was unjustified.

"Tesla publicly stated he made violent threats. The police refused to corroborate that claim." ... because Tesla "declined" to make the witness/es who received those threats available to the police.

That's a bit more contextual.
