In comparison, we've gone from a couple per day in the entire country to a several per day per state, and you don't think that increase is large?
No, I don't. Here a few things to consider:
1) The population in the US in 1970 was just over 203,000,000 and now sits at 314,000,000. Anytime you add over 100,000,000 people, everything is going to increase. This one is self explanatory, so I won't go further.
2) In the 1970's you can read about all of the domestic terrorist activity, killings, bombings, etc. and the entire decade doesn't equal as many deaths as just the Oklahoma City bombing. 9/11, Waco, The Unabomber, Anthrax, sniper attacks, Fort Hood, just to name a few, are part of the reason we are seeing beefier police presence and action.
3) Ruthless drug cartels are pushing new types of drugs and weapons.
4) In the 70's you couldn't go online and purchase armor piercing bullets, high powered assault rifles, or create complex and devastating car bombs and IED's like you can now.
Do you agree that technology has given criminals far more options, including cyber crimes, than what they had available to them in the 70's? Is it not rational to expect our police force to also use that technology to stop them and protect citizens?
I feel like I'm the only person here who is thinking outside of the last Fox News broadcast.
