To be clear this was initially stopped at the border as the old smoke detector he ordered was clearly labelled "contains radioactive material".
The authorities decided they wanted to build a case rather than stop it there though so they allowed the delivery to proceed. So it was delivered by a courier without protection because they knew it was harmless. They then subsequently sent in a full hazmat crew to close off the street. Not because they had to, they just had the courier deliver it after all. They closed off the street because the drama would apparently help the prosecution build a case of how dangerous this is.
UPS erroneously delivered the Thorium sample, not the plutonium, which was ordered many months earlier without being intercepted.
