[Marvel] What argument was used to blame Wanda for the bomb at the start of Civil War?

The Avengers track down an extremely dangerous ex-Hydra mercenary who is about to steal a biological weapon. They recover the weapon, but the mercenary detonates a suicide vest in the middle of a busy market. Wanda is there to contain the explosion, but unable to hold it anymore she throws it upwards, where it explodes against a building. Given the absolutely packed state of the market, it's a virtual guarantee she saved lives.

So how was she (and the Avengers by extension) blamed for this? without their intervention, many more people would have died to that bioweapon, millions possibly. Without Wanda, the bomb goes off in the market, killing dozens if not hundreds (on top of Cap). What even was the legal or ethical argument for blaming them and her specifically?

Because the Avengers just went there and did their mission without telling anybody about it or getting clearance.  They fought with terrorists in a crowded marketplace while a canister with an ultra-hazardous bioweapon was getting kicked around.

Isn't there a better way to do that?  Couldn't Falcon have just had his little flying tracker thing follow them out of the city?  Do you have to fight Hydra agents right that second?

Wanda was a brand new Avenger at the time, and not well trained.  She got blamed for it, but really it was the Avengers as a whole.  They ran around like Team America: World Police, and as a result a bunch of people from a notoriously bitchy nation got blown up (while nobody knew Wakanda had tech at the time, they were still really preachy and difficult to get along with).
