Such incidents happen with Rahul Gandhi. Generally, h is himself responsible for security lapses for the sake of excess proximity to people for popularity.
I think it is high time for Rahul to think about his personal security as there were many incidences in the past which took place even with tight security all around. I think one's personal security matters more than anything else and he should try to understand the fact that he could even serve the people and do his works even being under strict security...
It's a very serious issue. Although security arrangments involving Gandhi family appear to be quite satisfactory the young politician has to be more careful in his movement!
The difficulty with Rahul Gandhi is that he is adopting short cuts to popularize Congress by eating in Dalit home and mixing more freely with people. This approach is certainly a security risk.
