What does any of that have to do with your complaint that they were authorized to use force, which is clearly part of the standard search warrant procedure?
Why do you hate law and order?
I don't think the secret service agents were going to open fire on clearly identified FBI agents.
Your main issue seems to be you don't understand what a search warrant is.
Yes, super easy to overrun the armed militia that's ruled Gaza with an iron fist for nearly 20 years. All while Israel is dropping bombs on them. Super easy.
Incredible overlap between people who believe:
1) Cops shouldn't be allowed to bring their guns to execute a search warrant
and
2) Israel can kill civilians with impunity as long as suspected terrorists *might* be present.
