It's all outlined here:

https://www.benefits.va.gov/persona/veteran-incarcerated.asp

"VA disability compensation payments are reduced if a Veteran is convicted of a felony and imprisoned for more than 60 days."

 One argument for why benefits are reduced after 60 days of incarceration is because they are receiving full care by tax dollars while incarcerated.  Medical, food, clothing etc.  They can get those benefits back once released.

 As for the video this is just another example of separating one part of a large event and saying the entirety of all actions should be made from the information contained within this one hallway.

 For all we know the police holding the door were told to just let people in/out since they were planning an interior divert to a specific location and to wait for the response team.  I for one would not confront people at a ratio of 1 to 100 and attempt an arrest when there's a chance a mob would get my gun if they saw me trying to detain someone.  

 I also wouldn't enter a Federal building because a civilian waved me in, which is how this particular hallway entry began.  But if I were person number 99 entering how would I know?  But then again I'm at a darn protest to overthrow an election, so what should I think is happening?

 Some were convicted.

If any are being denied their VA benefits and have not been convicted, that appears to be illegal.

 My experience has been those that claim their VA benefits are revoked can not provide any indication of this.  No letter, and no reduction in payments in their bank accounts, but that's just my limited exposure.

 Is any legal representative of any of these Veterans making this claim?

You have to see it like it is. And it's like this:

If they crappity smacked up , then you can't give them a way out.
Even if they have been crappity smacked without them noticing.

If they want to undo the effect of getting crappity smacked, then you have to crappity smack them harder.

America must become a country that doesn't give a crappity smack.

It is simple;

If you want women to give birth to  children, you have to make sure they bear love babies. As long as you crappity smack women, you have to give them a way out.

Seriously? Fukkin VIDEO of cops allowing people to walk right by? Holding the door for them? You have No honesty in you.
If they were not WANTED Inside that building, then what explains the cops not trying to keep the door shut? You have to see what is going on.

Row, you just watched a video of the Cops allowing them in. They weren't trying to push them out. And the riotous Trump supporters were behaving peacefully. Yet,with video of what was happening, choose to ignore what your eyes are seeing and pretend that a picture of Hitler petting a dog is some analog?  

So far, it's looking like I'm the only person here who is able to type

I was wrong.

You should try it.

 Are any of the people in this specific video being prosecuted?
