Actually an organized militia isn't needed. As the bill of rights is just a small enumeration of our natural rights, and does not include all of them. They are solely there to remind the populace what our rights are even in the face of a tyrannical government. Funny enough your arguments now are why James Madison didn't want a bill of rights included as he felt that Natural Rights were too numerous to list, and people would think themselves limited to only the enumerated powers or confuse them into thinking the government granted them those rights. When, in fact, those rights are inherent to our very being.

Some Relevant reading:

" When in the Course of human events, it becomes necessary for one people to dissolve the political bands which have connected them with another, and to assume among the powers of the earth, the separate and equal station to which the Laws of Nature and of Nature's God entitle them, a decent respect to the opinions of mankind requires that they should declare the causes which impel them to the separation.

We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.

--That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, --That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness.

Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience hath shewn, that mankind are more disposed to suffer, while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed.

But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new Guards for their future security. "

-The Declaration of Independence.

So important they wrote it down, and signed it. (Broke it up for readability)

It's still very much a matter of privilege to afford a good enough attorney to get you off. Black people tend to get shot while sleeping and convicted postmortem.

I certainly wouldn't find anybody shooting an ICE "agent" as guilty if I was on the Jury, regardless of what a judge might say. Jury Nullification is an important right that every U.S. Citizen should know about, but never talk about inside a court house.

I refuse to put away people defending their community from a gestapo like force, regardless of the events surrounding said gestapo's death.

If you're asking about ICE officers, they've been given the authority to sign their own warrants.

I mentioned people organizing and fighting back in my earlier comment. I absolutely support it. But the main point is the organization.

And I really don’t think it’s unreasonable to suggest that, while sure they are doing whatever the fuck they want now, they have far more gross tools they can use. I think what we’re seeing right now is Trump trying to normalize the military protecting ICE.
