It is five minutes walk from the corner of Lamar and Main streets in Dallas, where a sniper killed five police officers this week, to Dealey Plaza, where another sniper killed president John F. Kennedy in 1963. What connects these events, other than guns and geography, is the raw, grainy footage that captured each.

If the silent, 27-second film of the Kennedy assassination made by Abraham Zapruder, inadvertent witness to history, became a symbol of America in the 1960s, it was also the precursor of what has sadly become a symbol of America in the 2010s: the ever-more-frequent cellphone videos showing shocking violence toward innocent men. This week, graphic footage of the deaths of Alton Sterling and Philando Castile led to the Black Lives Matter protest at which the Dallas officers were shot. At least one of the officers’ deaths was also captured on video.

Since Zapruder, technology has granted us vast increases in both the quantity and quality of these acts of witnessing. What it has not granted is greater access to truth. Just like JFK’s death, the deaths of Sterling and Castile may well remain disputed—as with the death of Eric Garner, which went unpunished despite being captured on camera in plain sight. We are still learning, painfully, that while the camera never lies, it never tells the whole truth, either.

Transparency and accountability are not the same thing. We should not confuse them, just as we should not confuse truth with evidence.Technology gives us ever more of the latter, but getting to the truth requires a very different process, which is still as susceptible to power and influence as it ever was. Until we understand and learn from that distinction, the camera footage won’t stop the killing.

Police used an unusual weapon to kill a man suspected of murdering five officers in Dallas on Thursday: A robot.

Dallas Police Chief David Brown told reporters during a press conference that police officers cornered a suspect and attempted to negotiate with him until the talks devolved into gunfire. Because of the danger to officers, Brown said law enforcement “saw no other option” but to use a robot carrying a bomb to kill the suspect.

That is it – Nigerian government should begin to acquire these weapons or better develop its version so that it can effectively manage the complex security challenges in the country.

Binyamin Netanyahu has just wrapped up a four-nation visit to Africa. Its governments, facing Boko Haram, al-Shabab and other extremist groups, are eager for Israeli security assistance. The trip underlines Israel’s shifting diplomatic strategy, away from relying on its Western allies and towards a broader approach. Israel is also trying to confront Iranian attempts to gain influence in the region, reports the Economist.

His itinerary included Uganda, Kenya, Rwanda and Ethiopia and he took part in a summit with the leaders of these countries as well as South Sudan, Zambia and Tanzania. The prime minister took with him 80 businesspeople, representing 50 Israeli companies working in Africa and launching a programme for economic co-operation with sub-Saharan African countries.

We hope Nigeria makes the list next time as Nigeria needs Israel for its expertise in  agriculture  and security.

Theranos, the embattled blood testing startup, has been dealt a major blow.

On Thursday evening, the company announced that it has received a notice from the Centers for Medicare and Medicaid Services (CMS), revoking its regulatory approval to operate and banning founder and CEO Elizabeth Holmes from running another lab for at least two years.

Among the sanctions are a monetary fine of an undisclosed amount and cancellation of the lab’s approval to receive Medicare and Medicaid payments for its services. The CMS’s decision is a result of its inspection of Theranos’s lab in Newark, Calif. last year, the company said in a press release.

I found these notes in one of my old notebooks . . . as I was reorganizing my desk a few days ago, after taking the CFA Level III exam for a 4th time early this month. I do not have any answers written down, but I assume I wrote them down as a starting point for further analyses, research, and discussion.
