No they don't thats stupid, "contamination" ibtw can be sorted out those are bullshit selectively used "lawfare" tactics and psyop stunt "fakings"....look you discover something like that the cops were called they did not respond accordingly VOP only started movingand collecting stuff AFTER literally days of begging for a real investigation stop inventing lies your head. BTW doorknobs may have many people touching for instance someone says they were never there etc. but their print shows up they lied. that can be used as evidence and the rest of the prints of others sorted out. that takes argument. You can't "dismiss" a crime scene because someone discovered it. People have been stabbed laying bloody and lives saved...its not an argument just a shill tactic. if we had un-corrupt non "controlled" but legit leos a real investigation would have occurred PLUS the environment which allowed this type of shit not permitted.
