Will the US government give money to the families who suffered a loss of a loved one in Boston?

When the towers came down on 9/11 the families of the people who were killed in that attack received federal money as sort of a life insurance pay out or combat pay, I am not sure what to call it.

If the Boston marathon attack is a terrorist plot tied into a Muslim group wanting to destroy and wreak havoc in America, then shouldn’t those families get money too for their loss? From what I understand it turns out our government had been tipped off about the older brother by Russia and we had investigated him to some extent.

I should add that I did not agree with all the pay outs for 9/11, but fair is fair.

So to sum up, I am interested to know if the families get tax payer money in this instance, and if you think they should.
