With the government essentially investigating itself, ultimately getting the truth about the attempted assassination of Trump is a longshot bet. From Robert W Malone, MD, MS, at malone.news:

After the complete and abject failure of the Secret Service in stopping the attempted assassination of our next President of the United States, one would expect that there would be an investigation, maybe even more than one.
But watching the news over the last few days has made it painfully clear that the investigations and the investigations of the investigators are to be never-ending. And despite assurances to the contrary, no one organization seems to be leading the way. Furthermore, whatever happened is being swept up into some classified dark hole, never to see the light of day.
The headlines from the past couple of days speak volumes:
The DHS leads the way:

Looks like the DHS Inspector General is investigating the Secret Service over their failure. Right? Well, that is weird, given that the United States Secret Service (USSS) is a federal law enforcement agency that operates under the Department of Homeland Security (DHS). They are one and the same.
Bwahaha! The photo is a funny.
Read that the SS is “appalled” at the mocking of Special Agent Karen Heffalumps the historic holstering czar.
Not too worried about a man KIA, several still in hospital?
The dreamboat that stood by Trump is a keeper though.
Also read that the FEW are apopleptic stating that Trump will end the sulfur world order, odd page says three attempts on Orange Roadrunner incoming courtesy of the FEW just as Archbishop (the man who should be Pope) Vigano said.
Trump stands tall like a rock while Jo Jo Brandon has the COV-LARP snwiffles again.
Riiight.
