There isn't much left too add to these incidences being very alarming. Though we can actually assume we will eventually get tagged again by one of these passing celestial object's, I suppose what concerns me more is the inability to spot such possible impacts of these objects too alert the public. NASA and some other groups claim too have approximately 95% of them under watchful eye, the thing I want to know is "How do they know that their 'Assumption' of 95% is accurate?"
Things are as they should be as far as our Cosmos is concerned, but not catching these NEO never seen before Comets/Asteroids or other space oriented debris leaves a bad taste in my mouth for even hearing them give such exacting number's.
I think they are Wrong, and they aren't able to do what they say they can do, but, IMHO, this remains a hopeful insight to the preparedness one must take, good example of this is Chelyabinsk, Russia, where an upper atmosphere asteroid exploded (Similar to Tunguska Event) and injured over 1500 people with shock wave caused, and this was from a small object on comparison of the ones that allegedly wiped out the dinosaurs.
QuoteCAPE CANAVERAL, Florida (Reuters) - An asteroid the size of a small truck zoomed past Earth four times closer than the moon on Saturday, the latest in a parade of visiting celestial objects that has raised awareness of potentially hazardous impacts on the planet.
NASA said Asteroid 2013 LR6 was discovered about a day before its closest approach to Earth, which occurred at 12:42 a.m. EDT (0442 GMT on Saturday) about 65,000 miles over the Southern Ocean, south of Tasmania, Australia.
The 30-foot-wide (10-metre-wide) asteroid posed no threat.
A week ago, the comparatively huge 1.7-mile-wide (2.7-km-wide) asteroid QE2, complete with its own moon in tow, passed 3.6 million miles (5.8 million km) from Earth.
While on February 15, a small asteroid exploded in the atmosphere over Chelyabinsk, Russia, leaving more than 1,500 people injured by flying glass and debris. That same day, an unrelated asteroid passed just 17,200 miles from Earth, closer than the networks of communication satellites that ring the planet.

Just a heads up, we will also be experiencing a meteor shower June 11th approximately 8:35 AM GMT in the upper quadrants of the Earth, should be amazing spectacle too view. With all you in mind, and hopefully some of your thought's over the NEO Observation centers predictions of the 95% they say they have covered.
