What are the chances of being killed by terrorists in the US?

How much money will the US spend over several deaths?

Yes, it’s horrible that 3 people were killed and 170+ were hurt by the terrorist bombing of the Boston Marathon.

But, how much will the US spend to prevent the next 3 deaths by terrorism?

Better yet, what do most people die from in the US?
Here is a link to some death statistics for 2010 www.cdc.gov...

Heart disease: 597,689
Cancer: 574,743
Chronic lower respiratory diseases: 138,080
Stroke (cerebrovascular diseases): 129,476
Accidents (unintentional injuries): 120,859
Alzheimer's disease: 83,494
Diabetes: 69,071
Nephritis, nephrotic syndrome, and nephrosis: 50,476
Influenza and Pneumonia: 50,097
Intentional self-harm (suicide): 38,364

In 2010, there were 19,392 firearm-related suicide deaths, and 11,078 firearm-related homicide deaths in the United States Firearms deaths
Interesting, almost 2/3’rds of the firearms deaths were suicide

Over the past 30 years, how many deaths in the US have come from terrorism? Perhaps as many as 3,500. That’s my quesstimate if you include 911, Oklahoma etc.

It’s clear to me that the chances of someone dyeing from a terrorist event are insignificant compared to disease, accidents or intentional self-harm.
So, how much money and effort will be expended to prevent those next few deaths?
Is it worth it?
What freedoms will we have to give up?

Or should we just try to continue living life as we do now?

I do think that there is an active effort to spend tax payer dollars on so much security but it is all pretty much a wasted effort.
