There's no legal requirement I know to show the warrant prior to seizure of material evidence based on a warrant. Do you know of any relevant case law that says otherwise?

Nope, just sincerely curious.

They need to show the warrant to enter suspects house but don't need to do it when seizing suspects property in public space. That's what confused me.

They don't need to show a warrant first in the case of no knock raids.
