But breaking the jammer would've been a good idea I don't think throwing something threw it would remember when peter threw the chair across the barrier in the animal clinic into deaton? If that would have broke the barrier in all likely hood Peter would have attacked Deaton. Well, in that instance the wood of the counter itself was made of rowan wood (rather than being just a thin line of mountain ash dust). I think?

Regardless, stands to reason that that would be harder to circumvent.
