There was a talk about a possible danger to Bush in June-July 2005.
There are many techniques for seeing such events, but Kota Chakra (aka Durga Chakra) is one important technique. Please read the excellent book on Kota Chakra by Sri KK Joshi, a student of Sri KN Rao.
You can get Kota chakra in JHora 7.02. Click on the "Chakras" tab and then on the "Kota Chakra" tab. Then click the right mouse button in the kota chakra window and select the pop-up menu item "view transits on this date". In the dialog box that comes up, enter the date, month, year and time. Kota chakra with the transits on the required date will be shown! It is ideal to have benefics (shown in green) in green areas and malefics (shows in red) in red areas.

When JFK was assassinated, Rahu and Ketu were transiting inside the fort in his Kota/Durga chakra. The dasa lord and maraka Jupiter too was in the fort.
When Indira Gandhi was assassinated, Rahu and Ketu were transiting inside the pillar of the fort in her Kota chakra.
When Rajiv Gandhi was assassinated, again Rahu and Ketu were transiting inside the pillar od the fort in his Kota chakra.
Kota chakra shows serious sicknesses also.
Take my chart (4th April 1970, 5:47:13 pm IST, Machilipatnam, India). Find the transits in Kota chakra around July 20, 2004. Sun, Rahu and Ketu were transiting inside the pillar and Mars and Saturn inside the fort (but not inside the pillar). All benefics were outside the fort. My health was terrible around that date.

If you use Kota Chakra principle, there is no danger to Bush in June-July 2005. An interesting time that comes up using Kota chakra is around March 31, 2008. Retrograde Saturn and Ketu transiting in Magha star and Rahu in Dhanishtha star form an axis on his natal 2nd/8th house. Moreover, Saturn, Rahu and Ketu will be inside the pillar in his Kota chakra, without any alleviating influences.
Some serious physical danger or sickness cannot be ruled out around that date.
Overall, I am more concerned about the second half of 2007 and the first half of 2008 than the second half of 2005.
May Jupiter's light shine on us,
