you can always claim "lack of evidence", if the investigation is cursory. that's what investigations are for - to obtain evidence.

"that's what investigations are for - to obtain evidence."

With the exception of catching criminals in the act of committing a crime, Investigations are supposed to occur before the arrests. In this case the PD got the order reversed. They made arrests for suspicious circumstances and are now I assume are proceeding with an investigation to find evidence of a crime. Not only will this get thrown out of court if it ever makes it that far, they have missed the opportunity to figure out what the true intent of the purchases was.
