Tragedy heaped on tragedy this week, all over the country. In very different news, Russell Wilson is finally gettin' some, but was it worth the wait? So we gotta ask ...

Tyson Beckford thinks the batch of cops who grew up over the last 25 years don't respect the power of the trigger enough because they became numb to it by playing video games.

Tyson talked to TMZ about the carnage this week, and he also has advice for black males ... on what to do and not to do when they get stopped by cops.

Definitely worth watching.

Demi Lovato is doin just fine after her recent split with Wilmer Valderrama ... at least that's what her twerkin' tells us.

Lovato's on tour with Nick Jonas and it's easy to see ... she likes to have some fun during her wardrobe changes. 

Miss her yet, Wilmer?

There is predictable fallout from the Dallas massacre in police departments all over the country. We've spoken with a number of cops and brass at LAPD and surrounding agencies ... and here are some top of mind concerns:

-- Cops are concerned about fake 911 calls ... that a copycat might use the emergency number to set up an ambush.

-- We're told cops are talking about carrying extra weapons to ensure they're prepared for the worst. It's a bigger issue now than ever before.

-- The brass is telling officers to always carry ballistic helmets, vests and other protective gear and have it instantly available.

-- There won't be 1-person patrol units for the foreseeable future.

-- Cops are being told not to advertise that they work in law enforcement while off duty.

That said, the brass is trying to reassure officers that not every call is an ambush and not to develop paranoia.

Cuba Gooding Jr. got emotional when our photog asked about the chance photo he took a few months ago with one of the slain Dallas cops.

Cuba mugged with Patrick Zamarripa back in February when the officer was on patrol in Dallas.

When we asked Cuba about it as he was leaving Firefly in Studio City, he welled up with tears.

Cuba has always been kind to cops ... joking around a few months ago with a pack of NYC officers.

Taylor Swift has nothing but time ... at least for her freshly-minted BF Tom Hiddleston.

Taylor was Tom's plus 1 as they arrived at the Gold Coast Airport in Australia.  Tom's there to film scenes for "Thor 3."

Romance ... you get AAdvantage miles.

Rev. Al Sharpton wants to make it clear ... he is NOT anti-cop.

We got Rev Al leaving NBC in NYC Friday, when he groused the Dallas killer set the anit-police brutality movement back significantly.

He also invoked the name of Dr. Martin Luther King Jr., saying the movement has been hurt by Thursday night's massacre.  

Levi Johnston needs to pay the piper now that the dust has settled in his custody war with Bristol Palin, and people are responding.

It appears Levi and wife Sunny set up a GoFundMe account for attorney's fees they racked up in their fight for Levi. He and Bristol settled the case ... they now have joint custody.

But lawyers need to get paid, so they set a goal of $5k, and as of this post they're raised more than $5,600.

Who knew? 

Before you watch Brock Lesnar lay it all on the line tonight at UFC 200 ... sprawl through these almost identical pictures and take your best shot at finding the differences between these two ultimate fighting photos. 

**HINT -- There are THREE differences in the above photographs!**
