They don't have to send anyone. All you have to do is not secure the perimeter (which they CLEARLY didn't) and after that everything will take care of itself.
There isn't a shortage of nuts with initiative in the US.
Somewhere theres a security guard who hasnt had a robbery in a year. So he decides "That door will be alright if i leave it unlocked for a couple hours".
There hasnt been an assasination attempt in a long time. Its easy to get caught slipping. Yall think just because they have a cute name like Secret Service that they dont have bad days. Or days where they feel lazy and do human shyt.
"These hillbillies love Trump,no need to climb on that dirty ass roof today"
What your saying is that at all these speeches there are snipers ACTIVELY TRYING to assasinate people. But because they see the perimeter is secure,they normally just drive off lol. Nah breh,theres probably gaffs and misteps all the time. Just not that many snipers any more. They are probably more worried about heavily armed shooters in 2024.
