Alongside the bomb, officers found a handwritten “direct action checklist” detailing the armor he needed, such as a gas mask, duct tape and flammable rags, the sheriff said.
I'm always amazed when these morons are caught with a "to-do" list of things they need to buy or do before they commit a crime that tend to incriminate them.
Looking at his list in the article referenced, is this guy so stupid that he had to write down "black shirt, black pants, black shoes, black gloves..."? I mean, was he afraid that he would accidentally show up in a day glo orange construction T-shirt and matching tutu with ballet slippers if he didn't write down on paper what he planned to wear that day?
looking at the picture of his "explosives", to me they look like they are fireworks rather than hardcore devices designed to massive destruction.
The giveaway is the green fuses which are common slow burning fuses used in fireworks. The brown cylindrical tube at the far left of the picture looks to be an insert from an aerial firework shell that is used to give off secondary effects in the sky after the main shell has gone off. We used to find several of these on the ground near our launch facility at Disneyland after each night's show that failed to ignite. We would just pick them up and store in a hazmat locker for disposal by incineration at a later time. Nothing too dangerous other than it might give someone a minor burn if they are holding it when it goes off.

His "hand grenade style explosives" look like thin plastic grenade replicas that he stuffed his fireworks into. If I'm not mistaken, a most damage from a grenade is caused by the outer casing fragmenting and spraying shrapnel into people nearby. These would merely melt and make a smokey fire. I do see a box of nails which might do some damage but with what look more like M-80's or cherry bombs, I don't thing there would be much of a shrapnel threat from his assortment of explosives.
It looks like this guy is similar to the morons who gathered at the Capitol on 1/6/20. They thought they were there to save the Country, when all they did was act foolishly and get themselves into trouble.
I think this antifa moron thought he was a bad ass explosives expert but he showed up better equipped to entertain the crowd with a fireworks show rather than extract maximum carnage.
