It pains me to say that this once fine organization appears to have a crisis of leadership at multiple levels. I have a number of former colleagues from that agency who are mystified by what is happening. First, you have the Columbia sex scandal. Next comes several high profile security lapses at the WH. Along the way there have been agents leaving their weapons on the toilet, agents swept up by local authorities so drunk that they cannot stand, etc.
The two most recent missteps highlight serious concerns with the SA leadership. On one hand, you have the ASAC for the Obama protection team driving his vehicle through an investigation scene while likely inebriated. His boss then makes the call to have the Uniform Division personnel at the scene let him go despite their concerns that he was drunk as a skunk. Now, we have a supervisor for Human Resources / Security Clearances being accused of sexual assault by another Secret Service employee while at the office for Christ sake. He too was apparently drunk after leaving his own promotion party when he couldn't keep his hands to himself (allegedly).
The new Director does not appear to be making the grade and fresh leadership is needed.
