I heard this the first time. Testimonial of a guy who claimed crates were dropped off and he was told not to look in them. Then they were left with him unguarded. Then he claimed he looked inside and then moved them somewhere else.

I say this is too incredible to believe. There is no way such a consignment would be left unattended before the time to use them with someone outside chain of command - huge risk. This was going around some months ago - there would have been follow up by now, and apart from anything else, the person finding crates of weapons would 100% have taken images of them.

I call clickbait. I actually think the plan to arm migrants so any chaos event becomes a massacre a reasonable fear - just don't think this sounds credible as stated. If it were to be done (and again, that is plausible when you know how evil they are) it would be done with much more control and weapons would absolutely not be left unattended for any time to be discovered. If real, where are the images? If you discovered this you would expect to be executed or disappeared so the safest action would be hair-on-fire publicity with video and images, whistleblower holding the guns up for you to see - giving his location - asking for a crowd to come.
